Hammered Copper Belt Buckle Vintage Handmade

Nice vintage handmade hammered copper belt buckle. The base is hammered and overlaid with a double crescent type design with raised rivets. The design looks familiar but I just can't place it. Nice and in good condition with just some visible solder on the loops on back. Unsigned. It measures 3" x 2" and can accommodate a belt up to1 1/4" wide.
