RGD, Radio Gramophone Development Co.Ltd., Newtown Row, Birmingham;

In 1929 the address is given as St Peter's Place, Broad Street, Birmingham, when they manufactured magnetic pick-ups and complete radiogramophones.


They were taken over by Regentone in 1952 but the R.G.D. brand name continued.

Around 1960/61 STC took over Ace, Argosy, Regentone and RGD. Marketing and distribution moved to the KB Factory in Footscray, Kent. Eventually the radios were made in the Far East, as were ITT KB. In the early to mid 70's the names RGD, Regentone and KB were all phased out and radios were sold in the UK as just "ITT".

This manufacturer was suggested by Konrad Birkner † 12.08.2014.
