The Courtenay 301A was manufactured for Turnbull & Jones Ltd by Radio Corporation of New Zealand Ltd in about 1948.

5-valve battery portable.

The 301A is quite different in appearance to the model 301, and is more akin to the model 402.  The chassis layout is also different.  There is a model 414(?) which looks identical but uses miniature valves, and is probably a later version of this model.

Valves (5): 1N5GT, 1A7GT, 1N5GT, 1H5GT, 1C5GT (to be confirmed)

Intermediate Frequency: 455kc/s

Frequency Bands: 1

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.
