Hey Rob, nice of you to add those old Bandai 1/48 scale tanks. I built every one of those Mk-IV's (D & H), Panther G's, Tiger I E's and Porsche Turret King Tigers, 251 Halftracks. They all had detailed interior engines, and althought I put them together in the tank, they were always hidden by their hatches. One thing though, Bandai, made very good kits.
