I have my Great Grandfather's gun it is mid to late 1800's. It has no name on it just Belgium Damascus on top of the barrel. Under the barrel it has ELG in an oval with a crown on top of the oval. It also has a 12 with a C under it in a diamond. Also has 18.2 on both barrels and looks like EL or EE in really fancy scroll this is all under the barrels close to the breach. There are two numbers one is 2 404 spaced like that. Then this number is hard to read but I think it is 811 03 ~ 02 spaced like that. It is missing the stock a long story about a rattler years ago. While trying to get a new stock made the hammers and firing pins and springs went missing. I want to fix it so my dad can shoot it he was the only one of seven the youngest that did not get to shoot it. I know about shooting it with modern ammo, we will check the barrels and shoot black powder loads. He just wants to shoot a squirrel with it one time. Thanks for the help.
