Original? Repro? RARE WW1 USMC Engineer Co. Patch w/ Engineer Collar Disc

Description

For auction is a WW1 USMC Engineer Company patch with a WW1 Engineer collar disc insignia. The patch is of multi-cloth construction (maybe silk?) and does not glow under UV light. I've not seen one like this, but it might be British or French made (or possibly a post-war veterans example?) I really don't know?? It's still a very nice, rare patch. I do believe the collar disc is original. Low starting bid, no reserve.
