Our Assessment: This British Enfield No.4 Mk. 1T sniper rifle began life in a very rare and historically significant configuration—as a No.1 Mk. VI rifle made at Enfield in 1931, part of a limited pre-production run that laid the foundation for what would become the No.4 series. Of the roughly 2,500 No.1 Mk. VI rifles produced, only about 1,400 were selected for conversion into No.4 Mk. 1T sniper rifles, making this example an extremely scarce piece of British military history. The conversion reflected both the adaptability of the Enfield design and the British military’s urgent need for accurate, long-range precision rifles during World War II. The “T” designation identifies rifles selected for their accuracy and fitted with a No.32 telescopic sight, as well as a wooden cheek rest on the buttstock. These sniper rifles served British and Commonwealth forces with distinction during WWII and into the postwar years. This rifle retains its Enfield receiver dated 1931 and still shows its early No.1 Mk. VI markings, making it one of the few rifles to bridge this transitional production period. It is fitted with a No.32 Mk.I scope made by R.E.L. of Canada, which remains in excellent condition with clear optics. Despite these changes, the bolt and magazine remain number-matched to the receiver. The bore is in solid shape, with defined rifling and moderate erosion, while the external finish retains about 70% of its green-painted war finish, with areas of wear revealing the bluing underneath.

Sniper rifles from WWII have become increasingly sought after, and this No.4 Mk. 1T—converted from a rare No.1 Mk. VI—is one of the most desirable variants. Combined with the intact optics, matched bolt and magazine, and historical markings, this rifle represents a crown jewel for collectors of British small arms. Whether displayed in a sniper rifle collection or appreciated for its unique developmental role in the Enfield family, this rifle offers exceptional historical and collectible value.
