So one of the "fun" parts of having multiple manufacturers of minis is that each may be labled 28mm or 1:56 or 1:48, but theres variation within for chunkyness, 'heroicness', true proportions, etc.
Here are comparison shots of the Perry Plastic Afrika Corps minis vs the standard Boltaction guys. There's definitely a bit more heft to the Warlord branded minis, or the Afrika Corps missed a meal somewhere.

The panzer 4 is one of the Revell snaptight 'toy' model. The tank is very chunky to the point of being mistaken for a Tiger, but the Taimya kits dont seem too bad.
