See .. the very interesting thing is the BritishDID do a drawing for the W&S scope to be used on the P.14 rifle. Attached is a cutout of this drawing. It dates 7-2-40, not knowing if the British prefer this weird way of putting the date or not, it may therefore had been either February or July 1940 when this drawing was made.
Note that this bracket puts the scope very high above the receiver. Additionally it sits on top of the receiver ring. And this is where it gets interesting - because the two pictures of the CanadianSniper with the W&S on his Eddystone P.14 clearly DOESN'T have this bracket.
As a result to this .. there may actually have been two versions of the W&S scope on the P.14 rifle. Or - what may also well had been - they just used the rail from the Ross Rifle, milled the receiver (especially the ears of the rear sight protector) to clear the scope, and that was the only one actually ever making it to production.
