Found this piece in the middle of an old mining site near piles and tunnels. Just curious what it came off of if anyone knows. It is about 1-3/4" tall and 3/4" wide at base. Thanks!
My first thought was some type of swivel, using the same principle as the 2 shown below, but I haven't been able to find a match to your design as yet.
PS: I cannot find one exactly like it either, but, then again, I haven't done lots of searching. But, it does looking like a ferrule that a line of some sort went through.
