ROCO Jimmys, 1ton trailers & M16s (2 engaged), towed 40mm (unknown source) & scratch built M51 carriage and ROCO M45 quad 50cal. mount in WWII western Europe.
Thanks guys.
It's plastic Rick. I think it was a UK version but I discarded the shield & replaced wheels/tires to complete the conversion to a US version of the 40mm Bofors. I've had it for decades.
