Other radios based on the same chassis:
The Oak Mantle was a 5-valve broadcast band Colt chassis in a solid oak (natural or dark coloured) cabinet.
This was the predecessor to the Planet model and is typically sighted with a 5B4 or 5B5 Bell Colt chassis fitted.
Radio and Electrical Review, June 1955
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.

Chassis Notes(most schematics can be clicked to download a full size version) Early versions used all rimlock valves, however later versions replaced the ECH41/42 with a noval ECH81. Some chassis' were stamped with 5B4, but not all of them.
