Made in England by BSA at the Shirley factory, this rifle is identified by the "M47C" maker code on the butt-socket and the "No4 Mk1" receiver marking. The combination affirms WWII-era BSA-Shirley production with period-correct military configuration.
The receiver is additionally stamped "F FTR 48," indicating a 1948 Factory Thorough Repair at ROF Fazakerley. This postwar overhaul returned rifles to service-ready condition and is a desirable, verifiable attribute for a No.4 Mk I from this period.
Chambered in .303 British, it features the standard 25.2 inch barrel and a 10-round detachable magazine system (10+1 capacity). The action is the Lee-Enfield pattern: bolt-action, rear-locking, and cock-on-close, known for quick cycling in service use.
It retains correct military furniture and fittings: two-piece hardwood stock with a brass buttplate and trap for the oiler/pull-through, and an upper handguard with longitudinal grooves. Sighting is via a protected blade front and a receiver-mounted aperture ladder rear. A bayonet boss at the muzzle accepts No.4 pattern bayonets.
The rifle wears a parkerized/blued finish with visible, legible markings throughout. The barrel shank bears an import/caliber marking "U.K. .303 BRIT." A khaki web sling with brass fittings is installed, and the included No.4 pattern magazine is matching-numbered to the rifle.
