The Bell Planet was manufactured by Bell Radio-Television Corporation Ltd in 1957.
This model is part of the Bell Colt series of radios.
The Planet was a Colt in a solid oak cabinet. Sales literature shows it to be a standard AM broadcast only model although JWS refers to it as a dual-wave. Its probable that there were dual wave sets sold in these unusual cabinets as well.
The solid oak cabinet was an oddity since most timber cabinets were veneer over ply. Being solid it was thicker that usual and appears quite chunky. They also seem prone to warping and cracking.
Bell Colts ran from 1951 through until 1980 - the longest running model of NZ built domestic radio. It saw many different engineering changes over the years, and the last few models dropped valves in favour of new transistor technology. There is considerable information on the main Colt page about this Kiwi icon.
