Hi Shayne,
Here is a link to the Canadian Military Remembrance Society website that you might find interesting.

This British Columbia organization has a C8A MACH ZL-1 currently undergoing restoration in Manitoba. It originally came from Williams Lake.
Army Motors #108 (the MVPA publication), Summer 2004, had an article on the history and restoration of this vehicle.
PM also sent to you.
