Good pictures, what is not clear is if it has an off-set bar (which I know it will not), which many of the so called batwing buckles have. Only a small selection are not brass & don't have off-set bars, these minority are mostly 18th C. Problem is many of the similar 19th C examples get confused. This pictutre only goes so far to help the minority, not the majority as argued on here many a time even when mixed with ONLY mid-late 19th C material & coins.
