I was relic hunting yesterday and dug this metal clasp. A fellow detectorist who knows Colonial and Civil War artifacts told me she has found a couple of these on Civil War battlefields; however she was not certain of the use. I was told by someone else that this is part of a saddle bag clasp. This was found in an area from which I've dug numerous buttons that date from the early 19th century. Any help on identifying this piece is appreciated.
