This is my Cossor 1035 Oscillograph (Oscilloscope).
It is massive and very heavy dual trace scope made in the 1950s.
I bought it many years ago, sold as seen from a local surplus equipment store.
The salesman back then told me it originally came from Jodrell Bank Telescope!
It worked well for many years until I got a more modern, smaller transistorised scope from a radio rally.
Since then it has resided at the back of my garage, gathering dust.
Yesterday I retrieved it while tidying-up the garage and brushed-off some of the dust ready to eventually put it on ebay.
The graticule cover has the name “Jennison” inscribed on it – so I typed “Jennison Jodrell Bank” into Google and straight away it showed results for:
Sir Roger Clifton Jennison (18 December 1922 – 29 December 2006) who worked as a radio astronomer at Jodrell Bank from the early 1950s.
It looks like it could be true – I just need to find a photo of him actually using it?
After a bit of googling I found a PDF article published by Ralph Spencer, Jodrell Bank Centre for Astrophysics University of Manchester, June 2017
Page 6 has a photo of Roger Jennison and Mrinal Das Gupta working on equipment for the experimental radio telescope in 1952
In the background (top left) of the photo is a Cossor 1035 Oscillograph!
