Key and Ring puzzle, brass. Stamp on the side that says Pat. Oct.23.94, which I assume means 1894. I couldn’t find it on the US Patent Search website. Simple puzzle, reproduced many times in slightly variant shapes.
Postage to be calculated after the auction, so please don’t pay until I send you the total with postage, which you can Paypal to tomjolly2020@hotmail.com. Preferably to Friends and Family.
