The first 3-valve (4-valve equivalent, taking into account the rectifier) Colt
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.
Please note that not all radios shown in this series were known as Colt's - the Planet, the Mercury etc were models in their own right - but they have a Colt chassis in them and so are included here as part of the wider Bell Colt dynasty.

This Colt uses standard tuning... the other three-valve set (the 'Cadet') uses permeability tuning (no tuning gang, moving slugs inside coils).
