The Courtenay model 108 was manufactured for Turnbull & Jones Ltd by Radio Corporation of New Zealand Ltd in 1934.

The Courtenay model 108 was the first aero-dial (round dial) set from Radio Corp NZ. The circuit is virtually identical to sighted 1934 Pacific 6-valve Dual Wave chassis' found in the likes of the Pacific Elite, Raleigh, etc. although Pacific used the 6.3V versions of the same valve lineup. (although a service bulletin for the Pacific shows 2.5V valves so there were possibly two versions - making it also possible that there are Courtenay model 108's with 6.3V valves).

The cabinet is similar to the model which supercedes the 108, the model 8.  That cabinet is up the other way though, with the speaker on the bottom.

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.
