Courtenay version of the Model 75 bandspread receiver - and the first bandspread radio designed and manufactured in New Zealand (and almost the first in the world). The model 75 is a 6-valve + magic eye set.
There is considerably more information on the model 75 under the Columbus version, which is virtually identical except for the cabinet design and dial glass branding.

General Construction Notes for Radio Corporation of New Zealand Ltd: The first digit of the serial number typically indicates the year of manufacture of RCNZ chassis' (although not the decade - that requires a little knowledge of the valves, construction, etc). Sets from around 1934 onwards were often (but not always) constructed in a distinctive pressed 'baking pan' style chassis, seemingly unique to RCNZ.
