Was there one auctioned that you know of?
Seeing as the P.14s were issued from Britishstocks and were never a general issue in Canada
, I'd suspect the 80(?) were almost all turned in before Canadian troops returned from Europe. I say "almost" because like scoped Ross Mk.III rifles, a few were obviously kept back as souvenirs by individuals or certain battalions. If the rifles were turned in the scopes probably were as well, as being of no further use except as scrap, just as was ordained for the W&S scopes in Canada in 1944, according to the correspondence that Clive Law found.
In fact probably all the small arms issued from British stocks were turned in; simpler to equip the much smaller post-war Canadian regular army with new than transport, store and refurbish rifles that had had seen a year or two of war service. One of the questions that should have been asked when the people that knew were still alive!
Most of the Canadian issue W&S scopes that have turned up seem to have come out of Quebec; I found two there myself. That could be simply because that's where Longue Pointe and some other major ordnance depots are or were.
Clearly a scrap dealer decided some were worth more as scopes than as scrap and didn't send them all off for the melt. Despite having a couple of pounds of bronze in them, they would only be "irony" scrap due to all the steel parts and probably not worth disassembly to get a higher metal price.
