The Philips 5V was manufactured by Radio Corporation of New Zealand Ltd in about 1933.

Made for Philips Lamps Ltd in NZ by Radio Corporation of NZ.  Possible that the V stood for Vertical as there were similar models with an H designator which were horizontal chest-style cabinets as opposed to tombstone cabinets.


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.
