Yes I did, No.310 as I recall, in the case, but could post photos if you want supporting evidence for my "claim"
Have you fired a Ross Mk.III with W&S scope mounted?
As for the P14s with W&S mounted, I've posted before that I have reliable reports of one on the loose here in Canadain the 1960s. My guess would be that it was brought back by a soldier or a battalion as IIRC a document posted here previously refers to a British
requirement that non-No.4 sniper rifles be turned in to stores as No.4(T)s were issued to replace them in late 1943 and early 1944.
From that we can conclude that either there were not sufficient No.4(T)s on hand to equip the Canadian Army sent to Italy, (quite likely in view of the comparative absence of No4(T)s from the late 1943 inventory) or they chose not to turn in the non-No.4 sniper rifles, presumably on the grounds that more would always be better, and since nothing better had been issued after two years of marking time in the UK, probably nothing more would!?
AFAIK, no collector in Canada has publicly stated that they own a P14 with W&S scope and that would tend to suggest they were all(?) scrapped. If by chance the serial numbers of those 80 odd scopes should ever show up on some document, we could at least determine if any of the 30+ known survivors from the 500 W&S scopes are among them, and that would in turn tell something about the fate of the rifles as almost all of those scopes have been found in Canada.
