This item came from the field where I found the James shell in October. I found it on the last trip. It was in a small area where a concentration of shell fragments came up. However, I was also getting close to a county road so it may have come from the road. Wanted to see if any of you recognized it. Since I'm not super knowledgeable with CW relics I'm afraid to throw anything away I find on this farm.

It's shaped like a checker. Made of steel or iron. The hole in the middle wasn't keyholed until I wire brushed it and the flaky corrosion broke loose.

Because of its design, that is called a keyhole fitting. It has nothing to do with locks, however, but rather they are used as a type of anchor to secure two boards together. A screw would be inserted in one board just far enough where its head would be protruding, which would then fit into the round opening of the plate which was attached to another board. The boards were then "slipped" so the screw head would slide into the smaller portion of the plate and lock the two boards together. I have seen these used primarily in upright piano construction, but I am sure they had all sorts of applications I am not familiar with.
