This is a very nice D.A. First Model, with 94% original nickel finish. This RARE 3 ¼” model was made in 1887. Only 5250 were made in 1877. The mechanical function is very good crisp and tight with S.N. 3858. The bore is very good bright and shiny with strong rifling. The grips are excellent as well. This was made about half way through the 1 year production.
