Thank for the informative post Gene. I measured the barrels and they are indeed 29.5". The barrel flat is clearly marked Leopold Bernard with cartouche to the left and right of his name. The other barrel flat has 2 words with a cartouche on the left and right of the words. I think he first word says "CANNONIER" then a mark like a star and then the word "PARIS". Nothing else is marked in the barrel flats. The underrib has the following numbers stamped to it. 1st set of number closest to the flats is 28949, second set of numbers is 1880, 3rd set on numbers in front of the barrel loop where the forend catches 25236, further down 1043 (serial number matching the action flat number. No proof marks or other markings on the barrels I will try to set up an account with imgur.com tomorrow and will post the pics I have taken so far. Anyone who can provide additional information about the gun, would be most welcome.Thank you in advance.
