I got this interesting milk car set the other day. Box is different and has prewar or early postwar label. The car and platform are brand new and unused. The parts envelope is sealed. The outer box is clean.
It's sad no one ever got to play with this fun car, but the condition makes it easier to understand.
Here's an unboxing of the set:
I think this set was put togther by Madison Hardware in late 1963. The box was made in Brooklyn in September 1963.
I think I have the cardboard peices and the parts in the box correctly. Nothing would be damaged with it packed this way, and the cardboard has marks from the staples and the car rubbing against it.
I'll add a reply with comparison photos to regular car set.
