I picked up a large lot of stuff the other night. Got one heck of a deal and it included three different sets of boxes. One is a Kennedy upper and lower, one is a craftsman top with master mechanics bottom, and the third I can't seem to identify. It seems to be heavy duty. Much thicker then most of the modern boxes I see. Does anyone have a clue what kind of box this is? There is no name on it.
I too believe it is a Proto based on the pulls.
