https://www.doublegunshop.com/forums/ubbthreads.php?ubb=showflat&Number=632347&page=4 https://www.gunbroker.com/item/998258318i have received the referenced "b. granet a dieppe" 12 gauge gun at the close of the week, and am generally pleased with the gun. the fit and finish is of obviously excellent workmanship - i would say equal, or better, than my la manu ideals. the barrels were proofed at 18.4, and measure; right @ .735, with 5 thou constriction, and left @ .732, with 48 thou. thus, the right is "out of proof" at .011 over, and the left is .008 over....the set is otherwise sound - 6.5cm chambers and cones appear unmolested, and tubes ring nicely. interestingly the right muzzle measures .730, which is .006 larger than the original 18.4 bore - so evidently when it was honed, some "backbored" choke was retained - makes me wonder if the original was a true cylinder?
the barrel set is marked "canons plume", and this is the first time i have had in hand such barrels. i had always assumed that was short-hand for "light weight", but now i can see that there is an actual difference. unlike the "I beam", one piece rib used on the la manu guns (which is centered between the tubes, and visible both as a "top rib" and a "bottom rib")....these barrels have only a top rib, a flat top tapered one that swamps toward the muzzles. it is revealed on the underside of the tubes, but leaves a great deal of the tubes unsupported. makes me wonder if it is a solid piece of metal, rather than hollow, or a framework device?
argo: the barrel proofs are carbon copies of your pictured guns in the same timeline....regrettably, my attempts at closely detailed photographs continue to disappoint me, so i will reference one of your posts/photos;
https://www.doublegunshop.com/forums/ubbthreads.php?ubb=showflat&Number=633240#Post633240 and say that other than the cm/mm change, the markings and their locations, for practical purposes are identical. for your records, i will note your serial # for these barrels should be 12455, rather than 12466....and i hope this post will result in more definite information regarding the maker and gun serial #.
in my research thus far, i have learned this gun was sold in 2021 by a german auction house in munich - which had evidently cataloged the gun 4 times before it was sold
https://www.lot-tissimo.com/en-gb/a...lot-997fdf46-b76f-4ca2-86dd-ad4200db26f1 their description indicates the barrels being reblacked, but i do not see any evidence - or, if so, it was an exceedingly good job. case colors appear to be original with limited wear on sharp edges and grip areas of the tangs. importer was tggi in mobile alabama, who has a storefront in munich. my seller bought the gun through a new england auctioneer.
proofs on the action flats include typical powder T, the numbers 13 and 16 (quite separately spaced), and an arched legend "medaille d'or" over 1900....formatted exactly like the two arched "grand prix" over 1900, that grace all d-d barrel sets after that award. there are two additional marks; one, a tiny shield - three pointed at top & single point at bottom - so small that i cannot make out any further details, and second, the name "moulard". the font and arrangement of these stamps echo the typical d-d stamps on the tubes and barrel flats....and lead me to wonder if this gun might be an actual d-d product. additionally, there is a stamp 13 inside the trigger guard - so i am led to think that may be the serial # of the gun.
