As more than 20 years has passed in some cases, I may remember incorrectly the manufacturers of the various kits and accessories, so If I get it wrong, I apologize in advance
The most difficult part of this kit was the nylon tank treads. Modelers today have greater access to photo-etched and resin parts, that were in their infancy 25 years ago (and the really good stuff was more than my allowance could afford). Getting soft rubber to conform to the road wheels in rough terrain proved the most challenging for me.
The 1:35 scale kit is Tamiya, the accessories and figure Verlinden, with a few scratch-built add-ons
