I've always thought that was a cool vehicle ever since my dad gave me a copy of "German Tanks of World War II" by Dr. F M von Senger und Etterlin about 40 years ago.
I'm almost exclusively modeling the Korean War, but doggone it I may have to make an exception and pick one of these up.
And the weathering and wear, in my opinion, is just right for your vehicle. I would expect a Paper Panzer '46 to be fairly fresh for paint and wear, and most wear would be from boots. You've hit the nail on the head.
