Ed asked my opinion on dating this gun since the advertiser seemed confused:

Here is my response. Welcome additions or corrections:
-- Boxlock; artisanal Saint-Etienne maker; barrels by Ronchard-Cizeren. (Owner says the gun dates from c1868 to 1878. Since A&D didn't patent the Boxlock until fall 1875 or publicize it until spring 1877, and there is no patent use number on the gun, this claim is preposterous.
-- 16 gauge 2 1/2" chambers in standard French barrel length.
-- Choked barrels (choke unknown). Rectifie *LOY* or LDY - LOY would have been the barrel borer. Don't know who that is.
-- 6.5 cm chamber means the gun was made between summer 1889 and summer 1912.
-- Proofed for PT means made after 1900.
-- Ronchard Cizeron, well known barrel maker in Saint Etienne (running bunny logo) died in 1899. In July 1901 his widow amalgamated Cizeron with Didier & cie (founded by Jean Pierre Didier) with Madam Ronchard as primary stock holder. The trademark press with "acier comprimé" (compressed steel) was registered in August 1904 by Didier & Cie.
So the gun was made between August 1904 and summer 1912. To further refine it, The gold medal stamp (Medaille d'or) could refer to several gold medals won by Didier & Cie from 1905-1911 - Liège (1905), London (1908), Brussels (1910), Turin (1911). And Jean Didier-Drevet, (father of Jean Pierre Didier), who invented the very light barrel "cannon plume" in 1899, won a gold medal in 1855 in Paris so it could conceivably refer to that too.
The genealogy and confused and incestuous intertwining of the families of gun-makers, makes getting the history of these companies a bit difficult - even French sites occasionally contradict themselves. But the gun is not rare.
Waiting for FAB500 input.
