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).
