Products: Model types Tube manufacturer

A.C. Cossor Ltd., Cossor House, Highbury Groove, London N.5, England.
A.C.Cossor can trace its roots back to 1859, when it was founded long before radio was discovered. They made thermometers and barometers, specialised electrical glassware, to later include an early cathode ray tube, made in 1902 and "R" valves for use in the later years of WWI at their first factory at Highbury, London.

In 1922, Cossor launched a radically new type of valve which they designed in-house, establishing their name in the frontrunners of radio. They went from strength to strength selling valves and radios kits, diversifying to electronic instruments, including an oscilloscope.
The company initially entered the business of manufacturing radio sets by selling their products in kit form, adopting the slogan "Kings of the Air", later manufacturing for sale, in 1930, their first complete model. The Highbury factory was continuously developed until 1932 when they ran out of space, resulting in a decision to build their second factory, at Leyton, where they made radio cabinets from 1934.

Founded: 1859
Production: 1927 -
Their household radio set brand name "Melody Maker" , introduced in 1927 for sets in kit form, was continued for 30 years until the late 50s and the odd example from my collection is shown elsewhere. Cossor's first TV receiver was advertised before regular transmissions had started, followed by a new receiver, demonstrated at the 1936 Radio Show. By 1938 they had the model 1210 using a 15 inch tube, very large by standards of the day, giving a picture, from which the model number was derived, of 12 inches by 10 inches. By 1939 Cossor, in common with all other leading manufacturers had joined the war effort, using their specific engineering expertise to develop the radar receiver for the Chain Home UK Radar Defence System. Their experience stood them in good stead, because after WWII they continued successfully in the field of radar. Manufacture of radio sets continued after the war with the number of different models getting less and less and ending with the introduction of tape recorders before the Cossor name petered out in the late 60s.
