Other trumpets with hexagonal valve casings
Vega, an American maker of musical instruments from Boston, made a octagonal trumpet as well. Model Hi-voice, serial number 40143, refurbished in 2012 dates probably from around 1950. Vega started in brass production with the aqcuisition Standard Band Instrument Company of Boston in 1909. The Vega trumpets and cornets were popular with jazz artists as well as the later big bands and solo artists such as Miles Davis; they enjoyed a comfortable niche in the professional market. However, producing handcrafted professional horns without keeping an eye to the increasing demand for student instruments, the company dropped their horn production to concentrate on their stringed instrument sales. In 1970 Vega was bought by C.F. Martin.
Jérôme Thibouville-Lamy, Paris
Also from France is this Bb and C trumpet from Jérôme Thibouville-Lamy, with dodecagonal valve casings and a lot of hexagonal details. It's named Hot Jazz Queen. The company is located at 58bis Rue Reamur, which could date the trumpet at 1932 or later.
A similar trumpet is engraved Nicholson's Special Jazz and was sold in 2017 through ebay.fr.
A Besson trumpet with fluted casings and hexagonal valve caps. Not a very clear picture but art deco engravings on the rimless bell.
A trumpet with ten sided valve casings, caps an bottoms and other hexagonal details is named Atlantic Special with on the bell the inscription Weihnachten (Christmas) 1937 and a removed inscription that the seller supposes was a nazi reference.
An octagonal trumpet that's owned by Richard Jereb, Vienna. The octagonal form has been consequently continued in different parts, like the caps of the water-keys (made of copper, not brass), junction rods, all pipe junctions. Also the finger ring and the handles of the slides are octagonal. No makers name or whatsoever, only an 1 on the middle valve casing. A stylized violin key on the tuning slide. Valve casings resemble Kühnl & Hoyer although the owner doesn't believe it could be West-Germany. The combination of brass and nickel silver means it's not older than 1970, according to Mario Weller, who's also convinced it's not Markneukirchen made.
A hexagonal bell and hexagonal valve casings and caps are distinct features of a trumpet that's branded Swing. Swing is believed to be a trade name of Steenhuysen, a brass manufacturing company in Brussels. Pierre Steenhuysen worked for Mahillon before he started his own workshop in 1926. His grandson bought Mahillon in 1970. The bell isn't hexagonal till the end, there's a saxophone player engraved on the bell. Steenhuysen made a Wonder model trumpet, and used similar hexagonal valve caps and bottoms and a rimless bell on other models/instruments, like the Swing Special.
A trumpet marked Wonder Super, round (rimless) bell with hexagonal valve casings, ferrules, valve caps and bottoms. Most probably from Belgium; Horn-u-copia lists a Wonder Super trombone engraved 'Fabrication Artistique'. Collector Peter Willemsen believes that Wonder Super also was a tradename of Steenhuysen.
Almost the same trumpet was sold under the name J van Dorpe, Courtrai (Kortrijk) also in Belgium. The main difference is the spin. It's engraved Model Wonder Professional.
De Prins Super
The hexagonal valve casings are also found on trumpets from Belgian maker De Prins from Antwerp. The De Prins Super trumpet features these hexagonal valve casings. De Prins and later Gebr. De Prins (brothers De Prins) were located in Antwerp, as of 1901. The brothers Karel, Gustaaf and Louis took over after WWI. Gebr. De Prins had a complete Super line of instruments. The company existed until 1980.

Another trumpet with hexagonal valve casings is branded Super-Vox Artiste Model and was offered through UK Ebay in 2018.
An 'important' difference with the above trumpets is the ribbed edge at the tubes.
Looking for some background of this Super-Vox trumpet I found a page of a catalog from Vox, the UK producer of amplifiers that emerged in the 60's and was made popular by the Beatles. In a 1964 and a 1965 price list there are apart from the amplifier stuff a few saxophone models advertised with the model name Vox Artist Model. On the Bassic-Sax website Helen Kahlke explains how the Thomas Organ Company in California tried to expand their Vox amp business to the wind bands with the Amplifonic, offering a whole bunch of wind instruments. But that was around 1968 and I think the above Super-Vox is much older than that.....
Then there's one other famous art deco trumpet from the thirties that has to be mentioned, the Conn 40b Vocabell, produced between 1932 and 1941 by Conn in Elkhart, USA. Octagonal valve casings, and many of them have a fine art deco engraving.
Another trumpet known for it's art deco engraving is the King Silvertone. Here's one from the early thirties.
