Wayne Fitzgerald is in Australia and has a Moke with a transverse A series 1275cc with a XSP prefix engine serial number XSP 2699/10. The Moke does not have an Australian compliance plate or any other obvious serial numbers to date the vehicle. So far he has not been able to find much information on the Moke build status or anything on XSP engines except Formula Junior and my Technical article on these engines.
If you can assist him please contact him via his email.
