I have been reading Chapter 9 "The MB in Canadian Service" by Eric Booth in Lloyd White's Book, Vol. 1 and will say this is a must have for Canadian MB owners.
It has the Canadian government contracts with Willys -Overland with accompanying letters. These contracts state specifically what was ordered and what additional equipment was included.
It also includes the Spare Parts Lists peculiar to the MB built for the Canadian Government.
The section he has on the lighting and modifications with government documentation and photos is amazing.
Army Motors Number 147 has an excellent review of the book, but the online ordering from Peter Ferris has a typographical error... a j instead of a g in the email address.
His correct email address is
pgcferris@sbcglobal.net
Oh, I found particularly interesting the letters back and forth from various Canadian Army staff the decision to use standard US Army MB in lieu of the Canadian Model based on the Marine Corps MB... really wild answers to some nagging questions on special models of the MB.
