Hi exfarmer

Great photos!
I have discovered that the RE Club has a dating service.
I better clarify that ... they have factory records...

The magneto - Wico - looks the same as Victa used.
This suggests to me this is a RE engine using some outside ancillaries-
Wico and Amal. [I do believe, now, this is not a Villiers engine].

This is a great story!
