I'm not sure the loco fits, it looks more like a DB Class 23 which weren't built until 1950. The DRG 01s were 4-6-2s not 2-6-2s
These are Kriegslokomotive whish operated in the war. The first two where built for tests, take service 1937. Decommsioned in 1973.
I have checked it twice
The most numerous of the Krieglsoks have even more wheels, that and I can't find any mention of a standard gauge 2-6-2 kriegslok :\ Still, god like work on them!
