I found this brass thing back in January at an 1800s demolished house site. It was in a photo I posted on another thread here, and I said I thought it was a keyhole cover. Well, today someone on Friendly Forum identified it as a sword hand guard. Bent up and probably broken, but that’s what it is. Did not expect that at all.
Here is a photo of a similar one also posted to friendly forum.
Glad I could rescue this from the brass scrap bin and put it with the relics. Who knew, a sword part in a backyard?
