It would pass for the ukraine 1944 or northern Italy spring 1945, as it is has later type wheels. I would agree there seems to be alot of the dunklegelb base coat showing and the brown and green seems to be rationed.but alot of these schemes were done by crews in the field with paste thinned with whatever came to hand, so variation in pattern and colour were inevitable.
If you want to see a completely artlessly applied paint scheme on a tiger I, look on the Kubinka museum website. http://www.tankmuseum.ru/p6.html .Ray charles could have done better!
zippy.
