5-valve broadcast band tablegram, featuring "Extended Frequency Featherweight" pickup. Possibly this refers to the Columbus turntable, models have been sighted with various turntables in them so its not clear, although JWS refers to the 19P as having a 3-speed belt-drive RCNZ turntable with 2 plug-in heads so at least that model does.
Model 19's ran for several years and there were 19R, 19N and 19P variants as well.
Cabinet: highly polished walnut
Intermediate Frequency: 455kc/s

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.
