US1121.)WWII USMC SHIPBOARD DETACHMENTS SLEEVE PATCH: still sewn to a cut fragment of USMC forest green wool officer's uniform fabric. Note that this patch is a very unique and unusual variety...it's machine embroidered on crimson wool fabric. Patch is machine applied and the back still has the original officer quality dark brown satin-like sleeve lining. This one's a very desirable treasure. EXC++++
