So if they had made 0000's of surplus scopes and H&H were only churning out 800 T's/Mth that means the other players building the T's must have been working at light speed I lifted this off another site on the purported No.s of T's produced if anyone can put a finger on it. On might assume due to the machining and work going into producing a T they would have kept exacting records of serials rather than just a standard No.4.
Ammoland,
A sniper variation of the Lee Enfield No 4 Rifle was used in World War Two, that used the No. 32 3.5x power scope and had a wooden cheekpiece. This model was adopted in 1942 and it was known as the No. 4 Mk 1 T. The earliest sniper rifles were converted from the Trials No. 4 Enfields at the Royal Small Arms Enfield Factory. Later that year Holland and Holland was contracted to convert select No. 4 infantry rifles to No. 4 Mk 1 T sniper rifles. British and Savage made rifles were selected for conversion. Somewhere between 23,177 and 26,442 rifles were converted by Holland and Holland. Long Branch made a small number of sniper rifles late in World War Two, in addition to those that were converted by Holland and Holland.
