5-valve broadcast band radio.
dual wave version is model 27 / 27N (octal / minature valve versions respectively)
Chassis Notes: Uses miniature valves (the 'N' designation is in keeping with RCNZ sets around this era that used them). Has gram input from factory.
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.
