Any Value? 1904 Side-by-Side 12-GA

[Max Cadenasso]

My uncle was helping my grandmother clean out some items in her & my grandpa's garage and they ran across my great uncle's double barrel shotgun. He died in the late-90's and I guess somehow the gun got in their garage. My grandma had no idea, she told my uncle to take it to the police. I'm glad I was able to reach my uncle in time to obtain the gun from him, as I'm the only one in the family that uses guns.

I'm not going to sell it but I am curious to know if there is any value to the gun. It's a double barrel side-by-side 12 gauge manufactured in 1904. All serials match. I had the chamber length measured by a reputable gunsmith who said it's setup for 2 3/4" shells and everything is mechanically good. Barrel is made of Vulcan Steel, not damascus. The only issue is that I guess at some point the metal on the gun was painted black to save it from rusting? Probably once the original blueing wore off. A lot of this black is actually worn off at this point but it's definitely noticeable. Does that make it pretty much worthless?

Either way I'm looking forward to getting this thing out to the range, should be a blast to shoot (pun partially intended).
