Addendum to previous,
I agree with bentaz, your gun is not a 1st, or even a makers 2nd. It is a general trade gun going by the very average engraving and layout. tracing the maker would be a task as so many records were lost to the war. In current condition it would sell for $100 to $150, restored $300 to $500, perhaps a bit more, but given it's heirloom status probably priceless to you and your family. Do it up, wall mount it if it turns out to be unsafe, or take it into the field with powder, wad, shot and card and shoot as your Grandad did, Cheers.
