Carrier Engine Identification

[Lynn Eades]

The LP2 and LP2A's had a 95 hp 24 stud truck engine.
The Canadian carriers (Universal Mk1*) were 85 h.p. 21 stud, but later on some units had their replaced with 24 stud motors.
The British Carriers are identified as No.1 MkI, or No.2, MkI., or No.3, Mk1. etc.etc etc. (is that o.k. Michael?)
This will likely raise an arguement, but at least in Jan. 1943 (the date of the Chilwell, Universal carriers, workshop instruction book. the book clearly states on page 3;
No.1 is the 65 hp engine, (21 stud, 18mm plugs)
No.2 is the 85 hp engine, and (21 stud,18 and 14mm plugs)
No.3 is the 95 hp engine (24 stud, 14mm plugs)
I have added the comments in brackets. Pretty much everything Ford had built by 1945, had been used in carriers.

Are you putting one together?
