VAdigger1988, for what it's worth to know... I searched all the way through the 616-page photographic encyclopedia book "American Military Belt Plates" (by O'Donnell & Campbell) for you, and I could not find a match for either the front or back or your buckle. Since it isn't shown in "The" book on American Military buckles and plates, I'm tending to agree that it is most likely a "patriotic motif" civilian-usage sash-buckle.
