There were no Pattern 14 or 1917 sniper rifles used in WWII, because there were no Pattern 14 or 1917 sniper rifles.Might have been a M1917 or an Enfield P14, both were still in occasional use a sniper rifles in WWII.
There were certainly "Pattern 14 sniper rifles" in the BRITISH Army in WWII.There were no Pattern 14 or 1917 sniper rifles used in WWII, because there were no Pattern 14 or 1917 sniper rifles.
I have to add, prior to CGI, the fabbed-up T34s were the best looking "Tigers" used on screen.
