I'm intrigued as to how you're going to supply power to the light. Wires down through the hull into the diorama base to leave access to a battery and switch?
spot on, just the same type, with the limited production cast hull, in fact this kit could be converted to a cast hull Lee gun tank. But I guess they saw limited service in the USA, probably as driver/crew trainers.
It's not by any chance the former for the brush guards (whatever they are)?
