Developed in the 1960s and deployed in the 1970s, the Enfield L42A1 was an upgrade of the Number 4 Mark I (T) sniper rifle. Configured for use with 7.62x51 NATO ammunition, fitted with a high pressure bolt head and hammer forged target barrel. Additionally, Model 32 Mark III scopes were also upgraded to match the new caliber. About half of the approximately 900 rifles made were condemned and destroyed post-service by the Ministry of Defense. Has standard sights and an import marked barrel. "19T" on top of the extractor assembly and bolt handle and "L42A1 D71" on the left side of the receiver. The old scope markings were lined out with the new NATO markings of "1240-99-963-2063/TEL.STRT.STG.L1A1/OS 2429 G.A." engraved on the tube, the base numbered to match the rifle, and "289E" and "290E" on the rear and front rings respectively. Has a smooth stock with "24791" stamped into the top of the wrist, a hardwood cheekpiece mounted to the comb and a brass buttplate with trapdoor. Included with the rifle is a green painted hardwood shipping case with a L42A1/L1A1 nomenclature plate on the inside, green painted steel cleaning kit case with cleaning supplies, leather sling, Parker Hale wooden clearing rod, latching green metal scope case, lens brush and a collapsing brass spyglass in a leather case with shoulder strap.
