Help with identifying this piece of electrical machinery from 1961?

Hello,

This is a bit random but I googled 'historical oscilloscopes forum' and ended up here:

Long story short, I am a writer and researcher and I woudl like to be able to identify what exactly this piece of equipment is. The photo is from 1961. I think it may be an oscilloscope? Any information most welcome!

Thank you,

Melissa

    It is an oscilloscope (the thing in front is much rarer now - it's an ashtray !)

    Looks like a Cossor 339 from probably 1940s.

    Cossor was a British company and made valves (electronic thermionic valves that is !).

    Are you able to tell us where the picture came from ?

    Thank you very much!

    The photo was taken in a workshop in Charlwood, Surrey in 1961 by a news reporter. There is a whole story around this but I wont bore you with the details as I'm afraid it has absolutely no connection with gadgets from the past. Slight smile

    it does however help tell me a little bit more about one of the people I am researching.

    Would  this have been an expensive item to have in the 1960's? He could well have had it for many years. His main business was as a market gardnener and a psychologist  but he seemed to be able to turn his hand to anything. He had a large 10 acre estate in Charlwood with several workshops on it and this is an image through the window of one of them.  He also had his own printing press in one of the other workshops.

    This may be an odd question, but were oscilloscopes ever used in any  way in the area of stage magic and/or spiritualism? This is known to have been another area of  interest for him.

    Thank you very much for identifying exactly which one it is.

    All the best,

    Melissa

    £45 (scope price when new) in 1942  is worth £2259 in 2022 money.

    The average weekly wage for a manual worker was £5.6 so the scope represents about 2 months wages - maybe a bit more than the inflation figure suggests.

    I don't know how stage magicians or spiritualists may have abused oscilloscopes Slight smile
