This is an Etched Panel Cased Colt 1877 Lightning 4 ½” barrel Pall Mall London with the normal British Proofs. The mechanical function is very good and the bore is very good, bright and shiny with strong rifling but does have some light frosting. There is a cleaning rod with a screwdriver and a full 20 round cartridge tray. It has a key but does not work in the lock. The box is fine and has a nice Pall Mall Label on the lid. The wood bottom has a small repair.
