I am unable to guarantee the date as there are no dates printed in the catalogue but it is believed to date from the 1950-60s. It shows models 1035 mk.III which I believe was introduced in the early 1950s through to the 2100 oscilloscope which is in the Radio Museum who estimate it to have been made in 1962 (https://www.radiomuseum.org/r/cossor_cossorscope_2100.html).

I have not tried to clean or restore this catalogue as I consider that it’s value is in it’s original condition.  The corners are very slightly “dog eared” and the first image shows a tear in the top left hand corner that comes down about 6in.  Also the last image shows a small impact damage to the lower end of the spine.

This has been stored in a pet free, smoke free home.  If you win more than one item, or win an item and have bid on an item that ends later, then please email me before paying and I will try to combine them into a single parcel and reduce your postage charge.  If you are able to avoid p&p costs collection is available from Bexleyheath in Kent but only if collected within 7 days of the auction finishing. In this case cash on collection is preferred.
