Thanks OutdoorAdv. I didn't see your reply before I posted about the plating. Good to know. I'll research that.
Agreed, it a nice shoe buckleHow little? Because whats left of the internal iron guts looks in the form of a Shoe Buckle, plus its curved which Knee buckles are not. So I'm going with small Shoe Buckle. That said its still a good 18th C find!
Thanks all. I think you're right. I have seen small oval curved frames called knee buckles, but I guess typically the tongue goes the other way, right? This does look more like a shoe buckle orientation. So small though. I don't know anything about silver plating, but it's definitely only on the face and just seems thick. No evidence of any flaking at all.
