G'day folks,
No worries Geoff, these things happen! I can't lay claim to very extensive knowledge of antique engines, but picked up a fair bit about the Buzacott/Rosebery verticals in the course of overhauling a 3hp as a high/tech school project back in the 70's.

A couple of forums I can recommend for local antique engine knowledge are the Down Under section of the Smokstak forums,
https://www.smokstak.com/forum/forumdisplay.php?f=115

and the local TOMM one; https://forums.tomm.com.au/index.php

Cheers,
Gadge
