The Rolls model CC was manufactured for Stevens & Sons by Radio (1936) Ltd in 1935.

Other radios based on the same chassis:

1935 6-valve dual-wave radio

Internally identical to the model CR (see the chassis notes at the bottom of this page for information about the C, R, S (etc) suffix). 

Rolls seems to have had a lot of different designs based around the CC / CR chassis in 1935, and there are many surviving examples at the time of writing - they are a good looking and well-engineered radio.

The design of this particular cabinet seems to be a simplified timber-only copy of the American made Zenith model 809, where the arched grill bars are in chrome.


The photographed model above is part of the Collection of Te Manawa Museums Trust, Palmerston North, Acc. No. 84/81/65.

Chassis Notes(most schematics can be clicked to download a full size version)

Two chassis models believed to exist.  Two shown above - early one used a 2A6 detector / first audio while later used a 2B7.  Early models also appears to have had round IF cans, while later has square - although this is circumstantial based on photos.

General Construction Notes for Radio (1936) Ltd:

Early Radio Ltd. schematics did not show the models, just the year, valves and bands, so some sleuthing is required to find the right one.

Early 30's Ultimate models with three digit model numbers indicated both the number of valves in the set, and the price it retailed for - for example, the model 856 was an 8-valve radio which retailed for $56 pounds. The equivalent Courier models were reversed, so an Ultimate 856 was a Courier 568 (theoretically, at least). This was the Auckland price though, and often the sets would retail for 1 or 2 pounds more in other centres, presumably to cover the freight cost of moving them around the country from the Auckland factory.

Note the use of old resistance terminology on older schematics: ω means ohms and Ω means megohms.

Some 1936-onward 3-letter chassis codes vary the last letter between brands, for example:
BBU - Ultimate model BB
BBR - Rolls (and Golden Knight) model BB
BBC - Courier model BB
All use the same chassis.

Golden Knight, Courier and Rolls appear to use the same copper-painted chassis while Ultimate chassis' are painted silver

After the war a new model code system was introduced, whereby radio models all began with R - the first model being the RA, a dual-wave 5-valve set commonly released in a pressed tin cabinet.
