Colt Second Model 1848 Dragoon Percussion Revolver
The Colt Second Model Dragoon Revolver was manufactured circa 1850 through to 1851 with a total of only about 2,700 produced. It continued the sequence from the First Model Dragoon from about serial number 8000 through to about 10700. Serial numbers are found on all major parts.
The revolver is in .44 caliber, weighs 4 pounds and 2 ounces and has a 7½ inch part round and part octagonal barrel. During its transition, parts were modified including the main-spring which changed from a V-spring to a flat design and the addition of a roller bearing where the hammer engages with the spring. The loading lever also used both the vertical and horizontal catch.
The barrel and cylinder were blued with casehardened frame, hammer and loading lever. The back-strap and square-back trigger-guard are of brass and silver-plated on commercial models and left plain on military contract revolvers. The six shot cylinder has rectangular cylinder stops with guide grooves and was roll engraved with the Texas Ranger and Comanche Indian fight scene. The revolver was furnished with one-piece walnut grips which were varnished for the commercial market and oil-stained for the military contracts. Military issue Second Model Dragoons have government inspector cartouches on the grips and letter stampings on various metal parts.
The barrel address reads from muzzle to breech either ‘-ADDRESS SAML COLT, NEW-YORK CITY-’ or ‘ADDRESS SAML COLT NEW-YORK CITY’ with the ‘COLT/PATENT’ stamping on the left side of the frame with ‘U.S.’ below on Government contract revolvers. The cylinder also has a roll-engraved panel marking in large letters ‘COLT’S PATENT’ along with a second panel of ‘MODEL U.S.M.R.’ (U.S. Mounted Rifles) with the serial number stamped within. Some models have the rarer marking of ‘U.S. DRAGOONS’ instead of the U.S.M.R. markings. A few Second Models were cut to accept all of the three types of detachable shoulder stocks. Variations include the NEW HAMPSHIRE and Massachusetts (MS) marked militia issues.
Philip Boulton of Southampton, England has collated and recorded a survival rate of at least 7.82% of the original production of First, Second and Third Dragoon revolvers. For in-depth reference on Colt Dragoon revolvers see ‘The Book of Colt Firearms- 3rd Edition’ by R.L. Wilson.
