Hi Jeff
Things are not always simple.
The Johnson Ironhorse (aka Cooper) certainly was used on small gen sets during
the war years ... it's just that I have no records of that occurring here.

Could it have occurred here? YES!
The great Knock & Kirby was selling Ironhorse 4-strokes pre-war, before
Cooper made their licenced engines here post-war.
[Note the reference to 'lighting plants']

AUS production was strictly controlled during the war years, with
many makers reverting to war-time production.

When I say 'small gen set' I mean portable - no C.I. fuel tanks.
Below, I show an AUS Amplion gen set, and the USA's Iron Horse.
Both Johnson and B&S made complete gen sets in the USA!

I guess those war days were desperate times.
It explains why USA makers could licence manufacture of their engines
outside their own North American factories.

It's a great question you ask, Jeff.
I wish I had a better answer.

Cheers
