Hello Taigatrommel66 !
You made a very good job, but lokos BR211 with numbers from 001 up to 042 have 4 double vents.
Model from Stepke have 6 single vents, this type od the loko was produced from 1970 (http://www.holzroller.de/). Most of yours work is unfortunately not real
You can easily correct some paintings (of course if you really want), for example test painting was also on 055 and 056 lokos, S-Bahn on 049 loko (modernly, i don't know historically).
BR242 also have 4 double vents from 001 number up to 022.
Stepke model have a small fault - riffles on the rahm, 6 vents lokos haven't got them.
I have a problem with BKK Bitterfeld loko, all is black, no textures.
