Hptm. Martin Vetter (Staka IV./KG 51) and Hungarians
 

I have a photo showing Hptm. Martin Vetter (Staka IV./KG 51, RK-Träger), a certain Hptm. Schlu... and several Hungarian air force officers, taken somewhere in Germany during training to Ju 88 bombers.
Another photo shows the funeral of a presumably Ju 88 crew, which died in an accident, with 4 German and 1 Hungarian airmen being killed during a training flight. The scene was set during wintertime.

Does anyone have an idea where and when these photos could have been taken?

Thanks,
