Great pics and a great brochure, I saw it on EBay and thought that Jack would be onto it. I did notice the Simplex and Villiers anomaly’s in the brochure.
I am just getting around to working on my Simplex powered Pace and I’m happy to find that the engine is in very good order, carb is clean, bore is clean and it has spark. Exhaust port is not carboned up which is a sign of the engine having had a service at sometime many years ago.
