I recently acquired an interesting uniform-related piece. It is made of some sort of plaster or ceramic with wood inlays. The person I bought it from said that the style was probably from the Mexican American war. The piece definitely has some age to it, so it's possible that this was used as some sort of mold. However, I really am not too sure about it. It has the the following text on the front: "78" and "U.S.W". There is also an eagle above the U.S.W.
Any help on this piece would be greatly appreciated!
