Coolgirl, PM me if Dagwood doesn't respond.
The catalogue shows a great range of hi-end output transformers, and indicates the importance of the core lamination material. It seems like Beacon used the same winding assembly and core stack outer dimensions for eg. variants like S06, S16 and S26, as the primary P-P winding resistance and leakage inductance are shown as the same.
Keen to hear from anyone with a Williamson amp with a Beacon transformers/choke

The 88C would appear to use a model number scheme that was introduced after 1958 (https://dalmura.com.au/static/Beacon%20Radio%201958%20Catalogue.pdf).
All I can suggest is to try any and all NZ on-line technical and audio forums, and the radio association (New Zealand Vintage Radio Society – Keeping New Zealand Radio History Alive).
And don't forget to post back here if you come across anything in years to come

Hi all,
Sorry I missed your requests, Ive not been on here for a while.
Here is a link to the copy I send Tim some time back

oldTnut, if you look through the 1958 catalog (linked to in post before yours) it indicates the R series is for power transformers, and yours is as you indicate - older than 1958.
No later catalog available so far - you may have to test for winding voltages, and use core size and winding dc resistances to estimate current ratings.
