Dual-wave version of the budget-model 24. 2 different known cabinets, most seem to have been sold in the round shouldered version.
Photos above show one with bakelite trims around the windows. This example was seen in Australia and could have been an export-only feature?

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.
