Back in the day (When I was an apprentice Elecronics/Instrumentation engineer at an atomic installation in the UK) there was a company called Bull Electrical who stocked only surplus equipment from large industrial sell-offs. It was a complete treasure trove of "what the hell is this?" moments, and the only way any of us had an interface with it was with their by-mail catalogue which was as disorganised as this website, and a complete joy to spend time with. You'd find things you never even thought existed, all at knock-down prices. I never bought anything crazy from them, just mundane stuff at low prices. But getting the catalogue from them was always an event - maybe once every six months - and it would spend all its time being borrowed and thumbed through on the loo during breaks.
Happy days!
I think this is their current website [1]. Certainly looks about right!
