This is a desirable example of a WWII M1C Garand sniper rifle manufactured by Springfield Armory in 1945, subsequently reconfigured into a U.S.M.C. MC-1 type sniper rifle. During WWII (late 1944-mid 1945) approximately 4,000 M1C sniper rifles were manufactured by Springfield Armory, most were refurbished at the start of the Korean War. Hundreds more were provided to NATO allies in the 1960s and hundreds more destroyed in the 1980/90s. Following the Korean War, the Marine Corps adopted the new/improved Stith Kollmorgen MC-1 4X telescopic sight with the larger Griffin & Howe mount adapted for use on the M1C sniper rifle. The Marines designated these rifles as the "1952 Sniper Rifle" and issued them in limited numbers from 1954 through 1967. All of the verified USMC 1952 MC-1 Sniper Rifles are built using original Springfield Armory Korean War rebuilds such as this rifle. This is a correct late production Griffin & Howe MC-1 type sniper scope mount with a first pattern Stith-Kollmorgen sniper scope. The scope tube is marked "MC 347-P". The objective eye-piece is roll marked in two lines: "4X DOUBLE STITH MOUNT S.A.TEX/KOLLMORGEN OPTICAL CORP. BROOKLYN NY." The scope is fitted with the improved, "audible click" windage and elevation knobs and the standard fine cross-hair reticle. The scope has the original blue/black type finish. The scope mount has the original markings: "GRIFFIN & HOWE INC. NEW YORK/PAT. #1.856,549 MAY 3, 1932" and is fitted unmarked scope rings with the later square end locking levers. Standard Springfield Armory receiver markings over serial number "3692207". The receiver is fitted with the M1C type scope bracket (base) with three new screws and two new taper pins and is numbered "369207 to match the rifle" on the side. The barrel is stamped "S-A-3-51" with the breech parkerized. Fitted with a four prong flash hider. With pistol grip stock with faint circled "P" proof on the wrist, leather cheekpiece (not screwed in) marked "MRT/1 52" on the right and stamped checkered trapdoor buttplate. Includes CMP certificate of authenticity identifying the rifle as an M1-C by serial number. An M1 Garand data sheet is also included
