I've got a 12" if you're interested. It's not on your list but if you're curious, I can help. I will go out on a limb and say that those wrenches are *probably* older than you! Mine dates to i think, 1945-8 ish. Says "Diamond Calk Horseshoe Co."
No chrome, no special features but, it's in pretty darn good shape considering...
I'm working on oics. but I'm up in the sticks in Minnesota so most means of contact are limited. (Nearly canucks!! well, not quite i guess. Only Rochester area today)
