I have to date found two in house publications for Cossor Staff and Agents.

The Radio Mail of which I have just a few examples date from the 1920's before Cossor started to manufacture even kit sets.

The Radio Mail describes A.C.Cossor as "Valve Manufacturer".


The Cossor Courier Dates from the 1930's.

The Cossor Courier seems to have started as a weekly pamphlet but develops into a monthly magazine.

The Magazine seems to be aimed at the dealerships and offers advanced information, training and sales advice.

As time allows I will add information from both publications but to start with I will just include some front covers from the Radio Mail and the Cossor Courier.

This copy of the Radio Mail is dated February 1926 this would give the date of the first issue as July 1925

The first couple of pages interesting the references to WW1 which was more than 7 years in the past suggests it was still very much a live topic. Its fairly clear when you read the whole document this is a gee up for sales of Cossor Valves. Despite not manufacturing sets at this time Cossor could clearly see the future was for them in the radio trade.
