I have been asked by a friend to identify a shotgun marked "A Chapu", brought back from World War II by his uncle, a military policeman. It is a 12 gauge sidelock ejector model employing a Purdey triple grip type action with 65mm chambers, and marked "A Chapu" and "Paris" on the water table, serial number 6301. The barrels are marked "Choke", and in fact measure modified and full.

I have some photographs, which, with some assistance, I can post.

Any assistance with identifying the maker will be appreciated.
