Rust Double

How much is a turn of the century Remington Arms double barrel shotgun in good shape worth?

Also, how does one get surface rust off the barrel? Would 00 steel wool do it? Both barrels have cocking levers and a lever that you push to the right. The shells pop up when you open it up after firing. I believe it is a 10 gauge. The butt plate has an ornate R over A on it for Remington Arms. It there a website for dating these shotguns?

Whatever you do, don’t try to fire that thing!

Some older guns were made with damascus steel barrels. Firing modern smokless ammunition through the gun could result in disaster.
