I remember seeing one of these many years ago in Denver, Colorado although I'm not sure of what model/year.
It was on Don Chews place. He was a M-H enthusiast and was compiling photos and data with a view to publishing a book about M-H production.
There has also been a fellow in Australia calling himself Robbo on the WW2 Dodge forum asking for information on the drive line for M-H light truck, not the artillery tractor, so he may have something.
