During the 90's I was talking to one of the Instrument Tech Sergeants on the PRE team (the annual inspection team) and he said that they occasionally came across old REL No2 binos and another US type, similar in size to the old No2's called 'stereoscopic vision' or was that a trade name for Bauch and Lomb - or both. These were usually with the OTC's (the University Officer Trg Corps) or the old public/private school Cadet Forces. If they were serviceable, that's where they'd stay! Most of these organisations worked on the well established 'old boys net' where 'the old boys' were now high up within the Armed Forces/Judiciary/Politics/Police/finance/banking....... you know the sort of thing. So the old boy net was a bit like wartime lend lease - but on a bigger scale!
