Manufactured by Bell Radio-Television Corporation Ltd in about 1958.
The cadet is a budget permeability-tuned 3-valve model - easy to spot because in place of the usual tuning gang are two metallic tubes.
Estimated introduction date - 1958
This might have been a replacement model for the Champ, also a 3-valve but with a traditional tuning gang, or it might have been another budget model alongside it.
