Late in the war mixed wheels were not uncommon. And as paint supplies ran out, camo colours went off standards. My only complaint is K&C reluctance to put sideskirts on at least some of the appropriate AFVs specifically Panthers, Stugs and Panzer IV. I know it would add to the cost and possibly be more prone to damage, but why not at least some versions with sideskirts. Even AFVs with a rail to hang detachable sideskirts on.
