The 'Clipper' brandname was introduced in around 1954.
Clipper was manufactured by Akrad Radio Corporation Ltd, they were distributed by G. A. Wooller & Co. Ltd. Currently there are 21 documented models.
Clipper was a brand used on many of the more budget-end receivers and car radios by Akrad.
An article titled "Home Appliances Exhibition at A. and P. Show" in the December 1954 issue of Radio and Electrical Review states, "...the new brand, Clipper, which has gained such popularity in the last few months.". This suggests that Clipper was new in 1954. Certainly no models have been seen at the time of writing that pre-date that (although the Clipper 6P2 was a 1952 model - the sighted model has a speaker dated 1955, suggesting it was probably still in production when the Clipper brand was introduced, and a Clipper variant was added to their lineup.
