This is a very late production Springfield Armory M1 Garand that was manufactured circa 1954 as a National Match rifle. It has the very scarce "X" prefix serial number, indicating the serial number was a duplicate that was accidently applied by Springfield Armory. As noted, this example was probably assembled as a National Match rifle, as its correctly fitted with a "NM" marked barrel, operating rod and correct "YO-1" bolt. Based on the date of the barrel, it could have been a late Type 1 or an early ungraded Type 2; however, it does not come with any documentation. These were all a late, last clean-up effort to expunge Springfield Armory of all M1 rifles and components prior to beginning the M14 production. As noted, the barrel is dated/marked "NM, Star proof, SA F6535446 10-54" with a P proof and the small DOD acceptance proof. It is also correctly marked "NM" on the left front exposed area of the barrel. As noted, it has the correct "YO-1" bolt, and it has a "6528290-SA" trigger housing, a late SA production hammer, and a early NM operating rod marked "7790722-SA". It has a standard wide base gas cylinder, a high hump gas cylinder lock and four slot gas plug. It is fitted with an early NM marked non-hooded rear sight and the "NM/.062" front sight. It is fitted with a new manufacture (non-bedded) walnut stock and standard (non-unitized) front handguard. The left side of the stock is stamped with a current CMP cartouche.
