I have a shotgun that I would like to try to identify and possibly get a value for it. I have very little information about the gun. It has patent dates of May 30th 1864, May ? June 11th, Nov 12th, Dec 24th, 18?? Dec 31st 1872, Sept 9th 1873, January 12th, March 18th 1874. On the left side of the barrell there is an R or B stamped... Cannot quite read it.
The gun is a fallling block single barrel. I have a picture of it and can email it if anyone can help to identify.
