Found this at the 18th century mansion I've been hunting today. I'm no buckle expert by a long shot and would appreciate your help with this. May not even be a buckle. It's small 1" x 7/8th. The center post on the reverse side appears to have been peened like you would expect to see on on a larger item done by a Blacksmith only much smaller.
Thanks! --Bill--
