Most often, TS+MB is allocated to Fliegertechnische Schule 3 in München (because a lot of TS+MB-marked planes were captured there).

These Fw 190s marked TS+MA are said to have been captured at Bayreuth-Bindlach. But there was no Fliegertechnische Schule stationed in Bayreuth. Also, at least one of the Fw 190s in the photos up there is clearly not marked TS+MA, but rather also TS+MB (or +MR, +MD, +MP?).

To complicate matters even further, photos from Fassberg at the war's end show at least one of the planes from Fliegertechnische Schule 2 marked "FTS", which stands for Fliegertechnische Schule I guess - and does not fit in with the TS+Mx markings practice. So yes, TS+Mx indicates some school, but there are many uncertainties about further details..

Why do you think there was no Fliegertechnische Schule in Bayreuth-Bindlach?
There was Fliegertechnische Schule 6 (1940 – Apr 45)
