The schematic of the Pacemaker suggests more US influence than British.
If you are referring the the "proper " valve numbers, rather than those bdk4752 or hfc21B that the british use I suppose you are correct.
When I do read English circuits I always have to have a substitution manual with me. As far as I know NZ did the same as AU and used American numbering systems.
Superadiotron, was the aussie brand of valves that we produced here, and were "mostly " from RCA, although Brimar and Philips also had factories here, and they ALL used the US system of numbering.
Apart from that, the circuit is pretty similar to any other superhet of the time. British OR American.
