Vintage unbuilt Bowser HO scale 100300 Union Pacific Challenger steam locomotive kit - Vintage unbuilt Bowser HO scale 100300 Union Pacific Challenger steam locomotive kit. The kit is complete but was in a box where the foam insert had decayed. I cleaned off most of the foam but a tiny bit is still there on the wheels. Comes in the original box with original paperwork and all parts.
