Picked this up this weekend, not knowing what it is, simply because I thought it was interesting and have never seen one! Yes, I realize that is not sound logic for a buying decision.
Anyway, did a quick search on the Ebay machine and judging by pictures only, it appears to be a Topps Framing Square with an 1892 patent. It's very "crusty" so I can't really read any of the inscriptions. I figured I'd ask the SMC group to see if they can ID what exactly I bought if possible? I didn't try to clean it at all since I'm not sure what it is, so this is how I brought it home!
Thoughts, if any? Also, if this isn't the correct spot for this type of question, maybe one of the mods would be kind enough to move it to the appropriate forum.
