My 71L###x with C No.32 Mk.3 scope is not a replacement scope. It is the Small Arms Limited factory original one and is all matching. Clive Law did write that MOST (but not all) of the 71L###x were fitted with C No.32 Mk.2 scopes. Remember that most Canadian made No.4 Mk.I* (T) sniping equipments were going direct to the British Army and in 1944-1945 most were being assembked concurrently, mostly for the same customer.
The late Clive Law in his book Without Warning mentioned several serial number batches for No.4 Mk.I* (T) sniper rifles i.e. 71L###x, 74L###x, 80L8### and 90L8###. He omitted the 68L###x batch. When I questioned him about it, he was aware of some in that number range but he had chosen, for reasons of his own, to not include this range. in my res easer has database I have recorded a number of the 68L###x sniper rifles.
I have a No.4 Mk.I* (T) from every one of those serial number batches plus one of the experimental Long Branch Scout Sniper Rifles with experimental R.E.L. Gimbal scope.
