I was hoping that you were going to say that!
I must check my notes but the first approaches were made from Canberra to the DND in Ottawa iun June 1940 about CMPs. I must now look to see if I cna find any evidence of any order placed for evaluation vehicles. It may be that there is no record and this is new history. Is the engine/serial number known please which will pin down its likely build month? Also, when it arrived?
Well done
