Hello cobja and Norm
Yes, this does present as a 3G 70cc Villiers engine.

I owe this information to Vintage Mowers and to NZ collector Greg Stokes.

Below is the specification.
We know what this engine spec was used on ... the 392X means ... Scott Bonnar!
This was an AUS built engine.

Hope this helps.
