Hey guys, I knew this would be the place to get answers. I'm no expert and never claimed to be. I was looking for my dad a pair of antique spurs when I ran across this gun. The letter looks official, but who knows? I've called Ohio Dept. of Natural Resources (ODNR) to see if they had any history on these guns and/or authenticate the letter. But nothing yet. X-mas and Muzzleloading season going on right now so I'm sure their busy. The gun says Remington Arms on each side of the receiver and nothing else. Exposed hammers and definetely 20 guage. I knew the last Remington SxS was made in about 1910, but have never even had my hands close to one, let alone know anything about them. I'm going to get pictures on very soon and I'm sure that will help. I'm a regular reader on this site and I knew better than to post w/o pictures. Sorry.
