15-cwt vs 30-cwt Wireless CMP

[Dennis Cardy]

Joe C. and others. The photo of the wireless truck you are referring to, is...yes.... a 30cwt, not a 15cwt. Bill Gregg spent hours in the Ottawa archives looking for appropriate pictures to illustrate his pioneering publication. In the process he came across many of the original photographs, used in the official D-Day handbook. When some of the original pics were not available, he chose similar ones. He then handed me a big stack of photo's and documents, put the whole thing together, and published it for him. Bill labeled this a 15 cwt wireless truck, and I pasted it into the layout as such. Mea Culpa. That one got by the both of us. Although, to be fair, they are very similar looking. Should have used a photo of the one now at Oshawa. BTW..it would seem, looking at its data plate..it was serial "number one" of a production run....perhaps for the aluminum bodied Gin-Palace's..?? The rear of the cab has the unique cutout for the canvas covered "speaking tube" between cab and rear body...ie..Driver and Radio crew communicating with each other. Anyway, sharp eyes detected the subtle differences..Especially as the 15cwt ladder does indeed curve over the top.

One comment on the data plates shown above: the chassis is listed as C15A but the publications are listed for C60L. I can't read the vehicle model plate. The presence of one inconsistency makes you wonder if there might be others. On the other hand, I know of very few CMPs that have absolutely no non-original parts (I certainly can't claim total originality for mine).

Grant, Correct me if I'm wrong, I think the C60L on the data plate refers to the appropriate lubrication manual.?

[Grant Bowker]

My understanding of the Publications plate is:
C-60-HB1 is the first version of the driver's handbook (incorporating daily maintenance chores performed by the driver, such as lubrication)
MB-C2 is the second version of the maintenance manual for the Chevrolet CMPs (excluding C60X, armored variants (C15tA Otter, Fox)) that goes into greater depth including rebuilding of engine, transmission, transfer case, winch and axles etc.
C-60L-03 is the third version of the parts list for the C60L (158" WB 3 ton truck chassis)
See the attached PDF scans of the covers of these manuals.

The publication plate looks replaced to me.
