Hi Ken
I can only offer some thoughts on this ...
The engine - a Midget MK2 98cc - was not made by Villiers Australia.
The lack of an crankcase X number apparently signifies that.
This engine was fitted to an imported machine.
I do not think the intake manifold is a standard Villiers part - that is the best clue.
[Apart from the crankcase stampings]
Perhaps a member will identify it.
Any evidence of date would have been stamped on the flywheel.
The MK2 was a post-war engine, used extensively on machinery, and
used up to the early 1960s.
