I recently received this double barrel, double hammer, double trigger 16 gauge from a family friend and need some help identifying it and figuring out what it’s worth. Lots of proof stamping under the barrel but I haven’t had any luck looking up of finding anything similar. “Marcel Murat” is stamped in several locations and I know the Murat family in France built guns but don’t see anything about the name Marcel. Any help on year built, origin or estimated value would be greatly appreciated. I attached pictures and could send more if needed to help figure this out.
