Tranter model 1879, 5-shot revolver. The revolver was manufactured in approximately 1880. Barrel is marked ""450"" on left side angle flat just below the rib. The revolver has approximately 90-93% of its original blue. We do not know the significance of the ""16359"" mark. Possibly a Victorian police I.D. mark or issue mark. This is a seldom seen revolver. The bore is bright and excellent with strong rifling. The action works perfectly. The grips are very good and have numerous light handling dents. No chips and no cracks. This was the last model Tranter made just before Tranters retirement in 1880. Very seldom found model in very good plus condition!
