OK, still trying to sort out the numbers for this tank. I don't know if s.Pz-Abt 503 had red with white outline? If so I think this will be 224.
Anyway, here it is with base of Dunkelgleb, then camo with a wash.
The camo came out way too harsh for me so I added a very thin 70/30 thinner/base mix back on top before the wash. This helped but gave more of a chalky look, so I used a raw umber wash and when dry wiped it with a Q-tip.
Next up mud, dirt, dust, and tracks...after decals of course.
Cheers,
Donovan
