That’s really nicely weathered, although a prime candidate to show when asking whether WW2 armour had a life expectancy long enough to ever get that messy. My personal view is it is down to the modeler and he’s done a blinding job here, slightly exaggerated for the sake of the art but all the better for it. It really gets the “feeling” across. Love it.
Question - why are the red star insignia partially painted out? And why both sides? What’s the story there?
