This is a gun that I inherited from my Maternal Grandparents. This gun was owned by my Grandfather's Uncle, Walter Coffey, who worked for the Railroad. My Grandmother told me that Uncle Walter was issued this revolver by the Railroad Co. Can anyone out there tell me more about this gun? The patent dates are visible on the top of the barrel. I can add that photo if helpful. You can see the photos of this gun in my albums. I'm not sure how else to get the photos from my albums to this post.
