Lee-Enfield rifles served as the core arm of the British military throughout the Empire and Commonwealth from the late 1800s until the mid-1900s. The Rifle No. 4 MK I, adopted in 1939 became a standard arm of British forces in World War II, but as the war progressed, particularly in the Far East against Japan, the military discovered shortcomings of the No.4 when employed in jungle or extreme terrain. In 1943, the Infantry Weapons Development Committee requested a shorter, lighter rifle, a call answered with trial rifles made up by simply shortening No. 4 rifles. In fact, the Lee-Enfield Rifle No. 5 Mk I nomenclature was not officially designated until 1944, after the carbine line had already gone into production.

Unique characteristics of the Lee-Enfield Rifle No. 5 MK I include a shortened barrel (and forearm/handguard), front sight protector wings with bayonet lug and flash hider assembly, modifications in the machining of some parts to further reducer weight, and a rubber kick pad with swing bar. The rear sight is graduated to 800 yards, reflecting the shorter field of fire encountered in dense jungle terrain. Aside from some additional modifications intended to lighten the rifle, the Lee-Enfield Rifle No. 5 MK I action resembles the No.4 rifle.

Produced in England by Royal Ordnance Factory (ROF) Fazakerley in November of 1944, the Lee-Enfield Rifle No. 5 MK I presented here is a wartime manufactured rifle. The receiver is marked ‘No. 5 MK I ROF(F)’ over ’11/44 D4485’ in two lines on the left side. The butt socket also carries the serial number on the left side. The right side of the receiver ring is marked with the British proof and export mark ‘crown/P’ over ‘England/broad arrow’ in three lines. The barrel is marked, from left to right, ‘crown/NP’ `303 “2·22” 18·5 TONS’, a civilian proof mark. Both this latter mark and the receiver ring marks are typical for surplus military arms directly entering the civilian market. The serial numbers all match on the receiver, butt socket, bolt, forearm, and magazine.

Overall, in very good condition with minor service handling marks on wood and minor service wear on metal. The top of the buttstock arsenal repaired near rubber kick pad. Many proof/inspector’s/other markings as noted in photos. Forend is squared with metal cap variety. This is a very, very nice-looking Rifle No. 5 MK I with crisp units marks on the buttstock, left side. Sling included. No import company marks observed. good bore that is clean, bright, with defined rifling.
