I think I have an imported Bridge Gun Co shotgun. It just has some markings that I have not seen before and is very ornate. I know that the gun was a hardware store gun but I am guessing this one was probably special ordered.
This is another of the guns I recieved from my father-in-law. But here are a few pictures, I hope yall can help me identify the makers marks.

Here you go. It's more fun if you do it yourself

Thanks!

I guess, if I am reading the marks right, I have a German made black powder shotgun.

It's a Belgian 12 gauge shotgun made between 1898-1924. The mark confusing you designates arms proved in conformity of German Proof Law of 1891

I don't see any marks indicating case length. Most of these European guns were chambered for a 2 1/2 inch, 65mm long case. Our cases are 2 3/4 inches, 70mm. Case length is measured on a fired case, not one still crimped. It's unwise to fire 70mm cases in a 65mm chamber, as the crimp can't open all the way, increasing the pressure.

After looking this long gun over I am not sure I would want to fire it. There is one Gunsmith (that I trust) in my area that I am planning to take it to to give it the once over. He deals with a lot of older long guns. Thanks for the measurements. I was guessing it would only fire the 2 1/2 inch shell but had no real idea.
