I have a Walter & Sons double barrel shotgun.
Markings on bottom of barrel under locking clip are JD2 / 10 over a C (10gadge)
also E over LG in a triangel with a crown at top.
This indicates Made in Liege Belgum.(parts anyway)
I think the gun was put together by W.S. around 1900.
The marking if yours are the same are between 1898 to 1914.
But they(Walter & Sons) probably made other guns from other manufacturers.
Hope this helps,look for other marks.
From 1895 to 1902
George Worthington was a hardware store in Cleveland, Ohio, from about 1890 to 1935. Single barrel shotguns were marked with his name by Crescent Arms Co and double barrel shotguns by J. Stevens Arms Co.
20 gauge marlin ou 2 triggers
Yes.
not with more than one gauge in one gun, but yes they make 12,16,20,28 gauge shotguns.
Check with your local gunsmith. No one would be making new parts, but lots of the old double and single barrel shotguns were similar and he might have something laying around that he can make fit.
Not published in any reference.
when did the make the smithsonian double barrel shotgun
You can have one made.
That's "superimposed" and does not add to or subtract from the value. It simple means the two barrels of a double-barrel shotgun are "over/under" instead of "side-by-side."
No
It's a French shotgun. Verny Carron was the maker, the shotguns tend to be well made guns.
