Short Magazine Lee-Enfield No. 1 Mk. III
The iconic Lee-Enfield rifle, the SMLE Mk III, was introduced on 26 January 1907, along with a Pattern 1907 (P'07) Sword bayonet and featured a simplified rear sight arrangement and a fixed, rather than a bolt-head-mounted sliding, charger guide. The design of the handguards and the magazine were also improved, and the chamber was adapted to fire the new Mk VII High Velocity spitzer .303 ammunition. Many early model rifles, of Magazine Lee Enfield (MLE), Magazine Lee Metford (MLM), and SMLE type, were upgraded to the Mk III standard. These are designated Mk IV Cond., with various asterisks denoting subtypes.
During the First World War, the standard SMLE Mk III was found to be too complicated to manufacture (an SMLE Mk III rifle cost the British Government £3/15/-), and demand was outstripping supply, so in late 1915 the Mk III* was introduced, which incorporated several changes, the most prominent of which were the deletion of the magazine cut-off, and the long range volley sights. The windage adjustment capability of the rear sight was also dispensed with, and the cocking piece was changed from a round knob to a serrated slab. Rifles with some or all of these features present are found, as the changes were implemented at different times in different factories and as stocks of existing parts were used. For example, there are some surviving SHTLE Mk III rifles made in 1916 at the Birmingham Small Arms Co in Victoria Australia that have the "pre 1915" round knob bolt action. The magazine cut-off was reinstated after the First World War ended, and not entirely dispensed with until 1942.
The inability of the principal manufacturers (RSAF Enfield, The Birmingham Small Arms Company Limited, and London Small Arms Co. Ltd) to meet military production demands led to the development of the "peddled scheme", which contracted out the production of whole rifles and rifle components to several shell companies.
The SMLE Mk III* (redesignated Rifle No.1 Mk III* in 1926) saw extensive service throughout the Second World War as well, especially in the North African, Italian, Pacific and Burmese theatres in the hands of British and Commonwealth forces. Australia and India retained and manufactured the SMLE Mk III* as their standard-issue rifle during the conflict, and the rifle remained in Australian military service through the Korean War, until it was replaced by the L1A1 SLR in the late 1950s. The Lithgow Small Arms Factory finally ceased production of the SMLE Mk III* in 1953.
