To me your drum looks like a piece together drum,the bottom rim is Sonor to me the T-rods also..The strainer is a Roxy strainer from the 60s'.Roxy drums were made in Germany but had not a thing to do with Sonor....Mikey

Roxy was a so-called stencil brand and were almost always badged as such. Not so for the company that actually made them, Tromsa. Tromsa for some reason very seldom badged their own drums. Since they also made heads , that at first were called R.K.B. but later Tromsa, I suspect they relied on the heads to designate the drums. I also have never seen a Roxy in such a format. The corresponding head style of snaredrum is a holdover from earlier days of marching drums and was very convenient for overcoming the vaguaries of weather. One could quickly tune both heads with 6 quick adjustments. These drums are still offered brand new in Germany and almost all German companies made them up to about 1970 and there is a popular vogue in Germany for shallow marching drums. These drums were also offered on beginner kits by many companies because they were cheap to produce.

I just reread this. It's true Mikey that Tromsa(Roxy) had nothing to do with Sonor: in general they were separate companies but in the early days of the Sonor rebuilding in West Germany, they relied on other companies to supply some parts that they could not make as yet. Footboards at least and possibly complete footpedals in the early 50's were Tromsa and Tromsa also made some of Sonors marching drums for them. As for the t-rods----those are Tromsa. Tromsa had 8mm slot t-rods and Sonor 9mm with a flat head top, not arced like these. Up until about 1957, Tromsa used a snare gate in the bottom hoop but switched to the two hole design for about 20 years. Tromsa hoops and Sonor hoops are similar but different. Sonor hoops have a decided lean inward to the upright section, Tromsa are pretty straight and the flare around the t-rod holes is fairly round on Tromsa and decidedly pointed on Sonor. The Sonor flange curls down on Sonor and just curls in on Tromsa. Tromsa hoops are generally more similar to Slingerland sticksavers than to Sonor, with the exception of the 2 hole snare cord gateway. This is an original drum.

i did some checking and your drum is catalogued in the 1969/70 Tromsa catalogue. model 204 13x5 and model 205 14x5. it is called the Amateur.

i have an Amateur I as a 13 x5 and its difference is that it has stickchopper hoops and the t-rods have a centre support. Phil.
