I have seen pix of panthers with road wheeles on the turret side like that. 

I would love to find spare parts like road wheeles and return rollers in plastic I can paint and "bolt on" to my tanks.  I am always looking for cool stuff to be on or near my tanks.   My goal is to shoot stills and movies of my tanks that are as close to "real" looking as I can get. 

Background, props and a tank or two set up to fool the kids, wife and any one else who will sit through it, thats my aim.
