What type of No 4 sniper do I have?

[CINDERS]

Roger if I may ask a question in relation to the scopes and their fitment;

Was it possible that in the transition through the various models of scopes MK 1, MK 2, Mk 2* & Mk 3 that as production of the T's went along the earlier scopes were left in stores with the rifles receiving the most up to date versions mainly the MK 2* & Mk 3.
Which would leave a surplus of the older scopes sitting in stores does/would the Army or H&H operate that way, was it ever use the earlier types up first!
Thanks for your time Roger.

P.S I did check my AK & S Mk 3 its a '44 mated to a BSA '44 T.
