Picked up a numbers matching .455 Triple Lock this afternoon! The serial number is 489 and the barrel isn’t marked with the caliber but per the markings and S/N I believe it is part of the British Military contract. I believe the date of manufacture should be right around 1910 The bore and cylinder are bright and shiny and the action has that pre war smoothness that we all love. The gun hasn’t been converted to 45 colt either. Anyway here are a few pictures.
