That would be an interesting pile to dig through.
iI see a king dick and a sweet machine tool.
I didn't really have a good look as it was nearly closing time. I did tip two bins out on the floor to rummage through. Did you notice the Walden-Worcester in the photo? Being stamped it is probably pre 1930's (I only know this because I googled it, thank whichever deity you believe in for Alloy Artifacts).
