Hello Mal

Thank you for that. I'm not good at TLAs grin
What Villiers engine chart? I have no docs that show 584X.

Any chance we can get scanned copies of your docs to verify
584X as a standard spec engine.

Oh. also, why do you think this engine would have been used
'especially on pumps'. It has no threaded shaft...?

Any information for the record most welcome.
I have stated what I have researched about the Ballarat Factory,
but I would like to record more about the engine models.

The MK10 & 12 engines would have been used on numerous horticultural
and agricultural applications. I'm just glad Chris is documenting one.
