CMP Instruction book
 

I thought this may be of interest. You probably have seen one of these but I thought I would share anyways. It's part of the reason I am interested in WWII MV's. It was my grandfather's. Date on inside is March 1940.

I have this book also Fifth Edition

I see yours is a Ford and mine is a Cheve book

I was suprised but it actually discusses both. Mind you it does refer to other manuals and publications a lot. Does yours mention the 6 x4 models?

It has C-8,4x2 C-15,4x2 ,C-15A,4x4,C-30S 4x4, C-60 4x4,CL-60 4x4, CTG FA Gun 4x4 July 1941 It was used a bit as the corners are bufft up , but other than that it good
