In Nigel Watsons first book ,on page 210. There is a list of engines used in universal carriers. (this is where I went wrong)
All the Canadian carriers(those with "*")are listed with the Canadian built engines (CO1UC-6097)and identified as No.3's.
There is no listing for a Canadian No1 or a No.2.
According to this page of Nigels book, ALL the Canadian universals are No.3's.
I now see on page 217 a contradictory item where the CO1UC -6097 ANH motor is listed as an 85 H.P. engine. As the 85H.P. engine is a No.2 (see photo)
From Dr. Greggs book, and various other material I agree with Rob

,and concede,

that your Carrier Ron, is a; No.2 MkII*
