This is a Model 1879 U.S. Trapdoor rifle 45-70 caliber. The barrel length is 32 5/8” and the serial number is 117844. Something of interest is the rack number of 165 on the right butt side of the stock. The bore is very good bright and shiny with strong rifling. The mechanical function is very good and tight. The markings are all about very good. No cracks or damage to the wood, only small storage dings and small dents. The metal is a deep plum blue color and I don’t see any remains of stock cartouches. This rifle would make a good shooter with proper loads.
