While Colt Single Action Army revolvers were often chambered for the same cartridges as Winchester's popular repeaters, they were not commonly chambered for cartridges by Smith & Wesson, their main competitors in the handgun market. This revolver is one of the exceptions, and by 1930 Colt switched to marking these revolvers "44 SPECIAL" which removed any mention of Smith & Wesson from their revolvers. It is one of only an estimated 506 Single Action Army revolvers manufactured for .44 S&W Special per "The 36 Calibers of the Colt Single Action Army" by David M. Brown. The accompanying factory letter lists this revolver with a 5 1/2 inch barrel in .44 S&W, blue finish, and hard rubber stocks. Under "Special Features" the letter confirms the revolver was shipped with an extra .44-40 caliber cylinder, an extra pair of wood stocks, and an extra pair of stocks with carved eagle motif which the revolver currently wears. All three grip sets and extra .44-40 WCF cylinder are included. Leaving the factory with an extra .44-40 WCF cylinder and three sets of grips likely makes this First Generation Peacemaker the only one of its kind shipped from Colt. The letter also states the revolver was shipped on April 18, 1927, to Bob Smith Sporting Goods Co. of Boston, Massachusetts, c/o George H. Crocker, Jr. (address unavailable). This was a single gun shipment. It is not often we catalog SAAs shipped to an individual, another standout feature of this already prized Colt collectible. George H. Crocker, Jr. (1893-1948) has been identified as the son of the International Paper Manufacturers Crocker & Burbank Assn. Crocker left Harvard to join the American Volunteer Motor Ambulance Corps (also known as the Norton-Harjes Ambulance Corps) prior to America's official entry into World War I. He was seriously injured aboard the steamer ship Sussex when it was torpedoed in the English Channel in March 1916. He was among three Americans injured from the German U-boat attack. After recovering from his injuries, Crocker enlisted in the U.S. Marine Corps in June 1918 and served with the 3rd Squadron of the 1st Marine Aviation Force in France. The 1st Marine Aviation Force provided bomber and fighter support for the Navy's Day Wing, Northern Bombing Group. He was commissioned a second lieutenant and honorably discharged in February 1919. After graduating Harvard, Crocker traveled to China in 1920 with the Pacific Development Corp. When he returned to the U.S., he began his career with the Old Colony Trust Company Bank and was a highly respected Boston-Cambridge-Brookline community member. He died at age 55 in July 1948 after years of ill health resulting from his World War I injuries. Scans of newspaper articles pertaining to Crocker as well as his obituary are included. The barrel has the two-line "RUSSIAN AND/S & W SPECIAL" followed by "44" marking on the left side. The other markings are standard including matching serial numbers on the frame, trigger guard and back strap. The matching assembly number "344" appears on the loading gate and rear of the frame. As stated, all three sets of grips confirmed in the factory letter are present, including the silver Rampant Colt medallion grips with the factory relief carved eagle and shield on the right panel. Documented factory carved stocks are rare, and when they are encountered, they are generally carved with a steer head. The eagle and shield motif is another rare feature on this SAA. The checkered hard rubber grips feature an embossed Rampant Colt at the tops. The plain walnut grips have silver Rampant Colt medallions. The included factory maroon box has the matching serial number on the bottom, end label with barrel length (5 1/2 inches), .44 caliber, and "RUBBER" for stocks, and an additional white label marked "S.&W. CARTRIDGE." above the hand marked matching serial number in ink. The box contains "Special Instructions" and "Shooting Suggestions" pamphlets.
