Hi
IanThat info you sent has proven crucial!
It is tragic that I find this exciting.

I had the patent on record, but associated with the
Little Trimmer.My best guess is that the
Little Trimmer was the 12"; the
Trimmer the 14"
We now know who invented the machine:
George Stanley Donaldson.
It was manufactured in Victoria, originally by
Donaldson Slattery & Company,
and then (probably) by
Australian Foundries and Engineering Limited.
The patent appears in the gallery ...
The square-bar cross-brace appears in the patent illustration.
I have more work to do on this one, and we look forward to your resto progress.
Many thanks.-----------------------------
