A large and somewhat ungainly looking revolver. Solid frame with removable trigger guard. Cylinder does not swing out and there is a thin loading gate. Bird's-head grips made of checkered hard rubber; walnut would be found on early models. Finish blued and case colored or nickel-plated. Model 1878 holds 6-shots and standard barrel lengths are 4.75, 5.5" and 7.5", with an ejector assembly and 3", 3.5" and 4" without. Standard chamberings for Model 1878 are .32-20, .38-40, .41 Colt, .44-40 and .45 Colt. This model was fairly well received because it is chambered for large calibers that were popular in that era. Colt manufactured 51,210 between 1878 and 1905. Antique models made before 1898 would be more desirable from an investment standpoint. NOTE: Add 15 percent premium for blued revolvers; 10- to 50 percent premium for calibers other than .44-40 or .45.
