Keilwerth brass instrument models
The catalogs and the information collected in the serial
number list below gives the following overview of Keilwerth brass instrument
models. Keilwerth didn't make rotary valve instruments and no other brass instruments
than trumpets, cornets, flugelhorns and trombones.

* the discussion about the system and the logic in Keilwerth sax modell names
is a
difficult one.
The main brass model names were the Toneking, the (Toneking) de Luxe and (Toneking) Super de Luxe,
later with the '2000' extension.
There are a few examples of a The New King trumpet (with early serial numbers:
0048 and 1468 or without). These have quite a different engraving, the one
flowerish, the other straight. They seem to be the quite similar to the
early Toneking instruments and untill now are only found in UK and Australia. I also found a reference to a
Julius Keilwerth
The New King de Luxe trombone and a
The New King
trombone with serial number 21. The New King was a model name used for JK saxophones from
before WWII until 1970.
There are quite a few Keilwerth 'Student' trumpets
and 'Student' trombones known. The Student instruments are described as the most
economically priced model in the Julius Keilwerth program, and
therefore especially suited to students and beginners. The Student saxophones and flutes (but no Student
trumpet/trombone) appear together with De Luxe 2000 and Super de Luxe 2000
instruments in the catalog with the 1979 pricelist. In the 1980's flyer Student
trumpets, trombones and saxophones and flutes are offered. Although serial numbers
for Student trumpets and trombones are in
between those of the Toneking and the Toneking 2000 series, I believe they were
made in the 80's, after the Toneking (de Luxe) 2000 instruments. I believe both
the Student and the Toneking 2000 instruments were supplied by other makers than
Keilwerth, using the serial numbers of those makers. For the 2000
instruments that maker probably was Blessing, for the Student instruments I'm
not sure. The Student saxophones in the 70's and 80's were first made by Amati,
and then by B&S, according to Helen Kahlke.
A trumpet and a flugelhorn are just named 'Julius Keilwerth'. They are
amongst the latest Keilwerth brass instruments
Then there are rare examples named Modell AT (trumpet) Toneking Exclusive
(trumpet) and Modell SX
(trombone). Also an ST trombone was mentioned in a Spanish Ebay-ad. Exclusive, SX and ST were also saxophone model
names from the end of the eighties, for the AT model name I have no clue.
The Keilwerth instruments were for a long time marked 'Made by Keilwerth, Germany' and not 'BRD'
or 'West Germany'. The use of BRD was discouraged by the authorities of the
Federal Republic of Germany itself, because it was considered to be derogatory (GDR)
jargon. The term was not banned by law, but its use was discouraged. The
trumpets in the 200.000 range are marked Julius Keilwerth W Germany. In 1973, the
Bundesgerichtshof made a ruling that Made in Germany does not
enable people to properly distinguish between the two Germanys of the
time, so 'Made in West Germany' and 'Made in GDR' became popular.
Design: King Super 20 replica
The Keilwerth (Toneking) de Luxe trumpet seems to be a
replica of the late 40's
H.N. White Cleveland King Super 20 trumpet, which according to
some sources was admired by Julius Keilwerth. The King Super 20 trumpets appear in the H.N.White catalog as of
1946 and remained unchanged until the
company was sold in 1965.
King Super 20, 1947 serial number 295886
Keilwerth De Luxe ca 1955 serial number 1104
King Super 20 Symphony Silversonic 1966 serial number 415937,
Keilwerth Toneking de Luxe ca 1965 serial number 12369
The Keilwerth trombones are stated to be Olds clones.
Keilwerth stencils branded otherwise
Keilwerth used at a certain point instruments made by others, but they also
made/sold instruments that were marketed under different other names, so called stencils.
These instruments were mainly sold in the VS and Canada.
A 'Made by Keilwerth' trumpet branded Kenwood, was sold on Ebay in
2014. It has the valve bow and guide of the early 'no serial' Keilwerth trumpets
and valves numbered 13,14 and 15 which makes me believe it's one of the oldest
Keilwerth stencils. ,
Kenwood valves numbered 13,14,15 source Ebay.com 2014
A 'Made by Keilwerth Germany' trumpet with
serial number 2058 is marked Van Hall. It's identical to the Keilwerth
Toneking. The serial would date it around 1960.
Van Hall trumpet Made by Keilwerth Germany, coll. Kaleb Hagel, Canada
It's not clear from where the trademark 'Van Hall' comes. There is a Kurath
(Pre Willson) Silver 3v BBb tuba stencilled as a Van Hall. Kurath started in
1950, and Van Hall 'made a load of bad instruments in Holland' according to a
source. There are several Van Hall (alto and tenor) saxophones, made by
Keilwerth with serial numbers dating them to 1968 - 1976. They often are named
'Van Hall Luxor'. Luxor was in the mid seventies/early eighties a German label
for instruments sourced from various makers and countries. Keilwerth made
saxophones for Luxor, according to Keilwerth
(Gabi Kermann).
The above non-Luxor Van Hall would be from an earlier date.
Another 'Made by Keilwerth Germany'trumpet, serial number 5345, bears the
model name Kembro. It's identical to a Toneking.

Hamilton
Some instruments 'Made by
Keilwerth' are marked 'Hamilton'. The one with serial number 22318 was purchased
from Grossman Music Corporation in the early 1960s, according to
Horn-u-Copia. Hamilton was a trade name of Grossman Music Co., a musical instrument distributor based
in Cleveland Ohio. It was founded by the brothers Henry and Julius as Grossman
Brothers in 1922 to distribute 'only Stringed and Band Instruments'. The serials
of these Keilwerth Hamiltons, betweeen 18.3xx and 22.3xx nicely fit into the Keilwerth range,
albeit that they would have been made around 1970 and not in the early 60's. There are other
Hamilton trumpets mentioned on Horn-u-Copia and
Trumpetherald.com with serial numbers in the 55.000-60.000 range, a HUC
Hamilton with serial 142.755 and one on
Ebay with serial 717.533, obviously from other
suppliers. The Hamilton Supreme is stated to be similar to the Blessing Standard.
One known serial number (59323) and dating of these trumpets to the early
fifties is consistent with the Blessing serial numbers, but another Hamilton
Supreme with serial 16448 is not.
Hamilton Supreme trumpet and cornet from 1953 Grossman catalog
La Sete
And there are 'La Sete' trumpets 'Made by Keilwerth Germany'. Those
also appear to be stencils for
the US market, a practice well known from the Keilwerth saxophones. La Sete is
believed to
have been the house brand of the Barthold brothers music store chain in Southern
California, it was also used by Splevins Music Center, 8834 W. Pico Boulevard of Los
Angeles, selling band instruments and dissolved in 1967. (The LA in La Sete
could thus refer to Los Angeles. 'Sete' is also found as Séte and
Seté). The La Sete trumpets in the 18.000 - 22.000 range definitely are
Keilwerth instruments, as they are marked 'Made by Keilwerth Germany'. In the
lower serial numbers (500-1800) there are instruments 'Made by Keilwerth' but
also instruments 'Made in Germany' that are identical to the Wohlrab 8N and 15N
model. Splevins also sold a La Sete
engraved trumpet 'Made by Wohlrab Germany'. Wohlrab is believed to be a
trademark from another Nauheim company, Bauerfeind. (Bauerfeind builds valvesets
and had a mr. Wohlrab making their trumpets). There are several La Sete
trumpets (in the 7000 range) marked only "Made in Germany". My guess
is that they are also from Bauerfeind as they have a lot similar with other
Wohlrab instruments. Then there are La Sete trumpets from
'Elkhart, Ind.", with serials in the 150.000 range. So while there were a few
'real' Keilwerth
trumpets sold under the La Sete brand, like Hamilton they sourced from other
makers as well.
And by the way, Elkhart, Indiana is where Blessing produced their trumpets,
the company that provided Keilwerth with trumpets in the later years. The La
Sete instruments from Elkhart are pretty similar to those Blessings/Keilwerths.
Keilwerth also produced/sold instruments under the Crestone brand.
These seem to have been sold in the fifties in Canada, according to a
thread on Trumpetmaster; trumpets and cornets and (also in the fifties)
saxophones as well. A pre 1954 Crestone cornet is reported, with 'Germany' on the
valves but not 'Made by Keilwerth'.
pre 1954 Crestone cornet, marked 10, 11, 12 and Germany on the valves
There also was an Keilwerth Eb tuba with the Crestone
label sold through Canadian auction site Kijiji in 2014, reported to be 'made in the
sixties',

And then there's a connection to Hopf. Horn-u-Copia states that Hopf in 1948 fled the Graslitz region and
relocated in Taunusstein-Wehen under the name Willy Hopf & Co. They started
making woodwinds after the relocation. For brass instruments, they stencilled the
products from their peers from the former home country. "The top line came from
Keilwerth", according to Horn-u-copia. That's confirmed by a statement of Gerhard Julius Keilwerth, who is
quoted on the
Markneukirchner Museum forum
saying that a Hopf New Sound trumpet was built by Julius Keilwerth somewhere
between 1965 und 1973.
But as the Hopf New Sound may look quite a lot like the Keilwerth Super de Luxe
with it's brass bows, there are a lot of differences; the
Hopf has a hexagonal moutpipe reciever and water key, a different 3rd slide
ring, the Keilwerth Super de Luxe has a micro tuner, a bell ring and two brackets
in the tuning slide. And the Hopf New Sound instruments don't have a serial
number as far as I know. One of them has valves numbered 169,170,171 which
doesn't point in the Keilwerth direction either. Norbert Böpple (www.jbs-brass.de)
told forum member Rainer H. that the Hopf was completely built bij Bauerfeind
for Keilwerth and then traded to Hopf. That seems to be more accurate: traded by
Keilwerth but not built by Keilwerth. The Hopf New Sound turns out to be
identical to certain Wohlrab instruments (Symphonic S),
Wohlrab being a Bauerfeind trademark.
Hopf & Keilwerth: different:

(Curt Wohlrab jun. managed a music shop, Musik Haus Wohlrab GmbH, after WWII.
It was located at the address Hauptstrasse 182 in Heidelberg, before the war the
address of a jewish owned umbrella shop Frank und Cie. Curt Wohlrab acquired
patents for his valveless trumpets in Germany and the USA. Bauerfeind had a man
named
Wohlrab building their trumpets. I guess Curt Wohlrab later on worked for
Bauerfeind or cooperated with them and gave his name to the Wohlrab
instruments.)
A trumpet marked Keytone Rexton is, according to the Ebay seller, also a
Wohlrab and identical to the Hopf New Sound.
Keytone Rexton (source Ebay2015)
There are also 'Keytone Solist the
Luxe' and 'Keytone Gold Star' trumpets that are identical to
Wohlrab/Bauerfeind instruments.
An interesting Keytone with the engraving '10 april 1958 PO USA - 3298
Special Services Property' added has similarities with some early Keilwerth trumpets
but also differences. It has no serial number and valve numbers 79,
80, 81 indicating a Graslitz provenance.
(Special Services were the entertainment branch of the US Army)
Keytone (source Ebay.com 2015)
Both Bauerfeind and Keilwerth were located in Nauheim, I can't rule it out but
for now I don't assume a direct relation between Keytone and Keilwerth.
There's a Toneking from Musik Barth in Stuttgart with the JK logo, bought
new in 1958, with totally different details.
And there's a Toneking (sr.nr. 1690) with an A and H added to the logo on the
bell. That makes it read like AKH, suggesting A.K. Hüttl, another Czech/German
instrumentmaker. This instrument was sold on Ebay in 2014 by a Detroit saxophone
shop. The seller added that "Rumor has it
that this horn was sent back from Germany with Detroit clarinetist and Herb
Couf, who eventually stenciled Keilwerth saxophones. We can neither confirm or
deny the story". .....
Superba 1
In an auction
from 2012 a Keilwerth Superba 1 is offered. The Superba 1 model name is used for
saxophones that were
made by Keilwerth for Herbert Couf. From 1965 to 1986, Herbert Couf, then
president of the WT Armstrong company, had three Keilwerth models stenciled for
him under the model name "H-Couf": the "Superba I", "Superba II" and "Royalist".
These instruments were built in Germany and
mainly corresponded to the Toneking Special (Superba I), Toneking (Superba
II) and New King (Royalist). Although this trumpet has a pinky hook that looks
familiar from older Keilwerths, Keilwerth didn't make trumpets themself in the
eighties anymore.
Keilwerth Superba 1, source Heritage Auctions 2012
Stencils marked Keilwerth: Blessing
It
seems that in later years Keilwerth procured instruments from Blessing, Elkhart
USA (said Helen Kahlke). Evidence is of course the similarity between Keilwerth and
Blessing marked instruments.

Keilwerth Toneking de Luxe serial nr. 240976
Blessing Scholastic serial nr. 376xxx
Keilwerth Toneking Super de Luxe 2000 serial nr. 227291
Other evidence can be found in the serial numbers (see serial number pages). Keilwerth brass instrument
numbers make a sudden jump, first to the 100.000 range, with mostly 'Student'
instruments and then to the 200.000 range with the 'De Luxe 2000' and 'Super de
Luxe 2000' models like the above flugelhorn. The 6-digit serial numbers
in the 200.000 range fit very well in the
Blessing serial number list; Blessing reached those in the
seventies. The 220.xxx to 330.xxx numbers would then place production of these
Keilwerth instruments (most of the Jazzophons included) in the 1975-1983 range
(from 1983 Blessing is said to have used a prefix to their numbers).
The Keilwerth Toneking De Luxe 2000 would thus be a Blessing Scholastic, with
identical design, valve block,valve caps ..... Blessing is said to have produced
also for other German sellers in the 70's and 80's. So based on the serial
numbers one could assume that Keilwerth bought their brass in
Elkhart from 1975 till 1980. A little more research is
needed to get the models sorted out.....
Stencils marked Keilwerth: the 100.000 range
I'm less certain about the 100.000 range. So far I discovered instruments with 6
digit numbers between 108.000 and 125.000 (and one with a 99.000 number). Like
the 200.000 upwards instruments, they don't have the hexagonal valve caps and
bottoms (the latest are to been seen on trumpets with a 46.xxx number). If these
were Blessings they would have been produced between 1962 and 1964. That's not
plausible, Keilwerth were making their 5 digit instruments untill at least 1970,
according to the sparse available data. All of the "Student' branded instruments
with a serial fall in this 100.000 range. Some of the Student instruments have a three or four
digit number, occasionnaly with a letter added. That's a way valve blocks were
marked in the Markneukirchen area, which would suggest these instruments were
made in Germany. For now my hypothesis is that
these instruments (at least part of them) were provided bij VEB B&S in Markneukirchen/Klingenthal. They
made amongst others the Weltklang and Bandmaster instruments, on these instruments similar
three or four digit numbers with a letter are found, indicating the maker of
the valve block. The (sparse) serial numbers on the Student instruments then
would come from that East German company. Based on the catalogs above my
other hypothesis is that they date from the (early) 80's.

York
In 2001 Schreiber-Keilwerth built a new factory in
Markneukirchen for the production of wind instruments and brass instrument
parts.

They made parts for the British
Besson instruments and
Boosey and Hawkes Sovereign cornets (amongst others?). As of 2006 Schreiber-Keilwerth
entered the brass marked again
with a line of instruments under the
York brand,
completely manufactued in Markneukirchen.
The line up consisted of 24 instruments, based on two formats, the 'Preference'
and the 'Eminence'. Here's a
York catalog of those days. They were descendants of the former Besson ranges (Schreiber
already had all the requisite tooling etc because of the break up of Besson),
but the company claimed there had been major improvements, refinements and
enhancements, as well as cosmetic changes to the all new range. They started
producing a 'Preference' and 'Eminence' model
cornet and euphonium as well as 'Preference'
flugelhorn, tenor horn, baritone, EEb tuba and BBb tuba, with the possibility of
additions to follow. No trumpets or trombones, as far as I'm aware of. The York line failed to find their place in the brass band
world and was discontinued when Buffet-Crampon acquired Schreiber-Keilwerth in
2010.

Not Keilwerth: Toneking by Amati
There are some Toneking trumpets without the Keilwerth logo, saying 'Made in
Czechoslovakia' on the leadpipe. Sellers state that these are Amati trumpets,
which could be true. Amati used the name Toneking, until the legal battle with Keilwerth ended
in 1955 with Julius Keilwerth as winner. Maybe this trumpet dates from that
period, but it might also be newer, as the case looks more 70's/80's.

Czechoslovakia' in 2014 offered on the Mexican auction site Mercado libre.

Ebay.com
Interesting is that on the
justanswer site someone mentions a Toneking trumpet that has the word
Bohemia on it. That would date it before 1918, when Bohemia became part of the
new post WWI state of Czecho slovakia. The expert on the site answers that the
piece is circa 1890-1915 and that the brand was only around for about 6 years.
Not Keilwerth: Toneking by New York Band Instrument Co.
The name Toneking is used by other makers as well, having no known relation
with Keilwerth. It was for example the house
brand of the New York Band
Instrument Company from East 14th Street, New York.
Catalog Nr. 8 New York Band Instrument Co. ca 1920's
They used it for different instruments, like cornets, trumpets,
french horns, (valve) trombones, mellophones but also ukeleles and banjos. New York Musical Instrument Co
started as dealers and importers in 1915, later changed their name to New York
Band Instrument Co and reportedly went out of business in 1950. So there's no
reason to suppose a relation with Keilwerth. Horn-u-copia.net lists
several NY Band Company instruments.

Not Julius Keilwerth: Josef Keilwerth
There are some trumpets around marked
Josef Keilwerth.
Josef Keilwerth was an instrumentmaker in
Graslitz. He was born in 1887, a few years after Johann Baptist, the father
of Julius. Josef Keilwerth
lived and worked at the Berggasse 736 (now Na Kopečku 736, Kraslice). In August
1946 he was expelled like most of the German population in the former
Sudetenland after WWII. He was listed to leave by train to Bavaria, together
with his wife Anna and daughters Margaretha and Gertrud. These instruments are to be dated before WWII
because they have the German name for Kraslice. 736 is the house number.

Keilwerth brass mouthpieces



Left a 1958 traditional trumpet mouthpiece, middle the characteristic shape of
the later Julius Keilwerth trumpet mouthpieces; to the right a
ca. 1958 trombone mouthpiece and a newer one..
Keilwerth brass serial numbers
Keilwerth brass serial numbers are on two
separate pages, page
1 (0 - 40.000)
page 2 (40.000 - 340.000)
There are
serial
number lists of Keilwerth saxophones around but there is no such thing for
their brass instruments. Below you'll find a list of instruments and numbers
that were traded through Ebay, Quoka and such, with information added from sites
like Trompetenforum.de (where Brigantiumjazz triggered me to make this list),
Trumpetherald.com, Trumpetmaster.com, Horn-u-copia and the Yorkmaster public
pictures at Yahoo. There seems to be no relation whatsoever between the
serial
numbers of Keilwerth saxophones and their brass instrument serial numbers.
The serial number list of brass instruments has more than 500 entries,
that's maybe 1 percent of Keilwerth brass production. It shows a fairly continuous
serie up to number 30658, with a few examples of every 1000. Then, after a few
incidental Tonekings, new models show up, like the 2000 and 3000 series and the
Student. The jump, first to the 100.xxx range, with mostly 'Student' instruments
and then to the 200.xxx range with the 'De Luxe 2000' and 'Super de Luxe 2000'
models could originate in other makers providing the instruments, as stated
above. Here the gaps between the numbers are much larger. That's probably
because they are part of a serial number list that includes the makers 'own'
instruments as well as other stencils. And maybe also because these are newer
and still with their original owners, so they down't show up on Ebay and other
sites?
There also are quite a few Keilwerth trumpets and trombones
listed without a serial number. They stand for a few thousand Keilwerth
instrument of what I think is their earliest production.

If you note any discrepancies, or have additional information concerning the
Keilwerth history and Keilwerth brass instruments, please
contact me.
Additionally, I would be grateful to anyone who owns a Keilwerth brass
instrument not listed to
contact me with the name, type and serial number (etc.). It would be nice to
build the list also using other horns than those that are being sold.
