Dug my first shoe buckle and it’s marked Paris 1866! There are still tiny traces of the gilt. I don’t know much about these and would love to know more about this type of buckle if anyone can help.
Very nice find. I have a similar one with no date though. I was informed it is a waist adjuster or fastener, though I can't remember the exact term. Bet you find other relics in the area. Good luck out there.
