Well I picked the boxes up,they are stenciled 1971 on the bottom.
The paint is a little scuffed up, down to bare here and there, but I like it.
The none roller slides are growing on me, I did take them out and clean them, used Fluid Film to lube them, I love the stuff.
The boxes seem to be built like most others I see ,seems like the same slides anyway.
I will try to post a pic.
