Just saw this in a book, and figured I'd scan the pic and post it.
Was this sucker an artillery mover? Supply mover? Both?
It certainly looks like it was built purely for the war. It certainly does not look like an agricultural model.
When I first saw it, I thought the book must have got it wrong, it must be a tracked carrier from the 30's! But, it is apparently a WWI French vehicle. Really cool looking!
From memory it was originally a tractor but also got pressed into service for general duties. I do have some details at home so I'll add it to my list of things to do on Sunday (unless someone supplies details in the meantime).
The vehicle is indeed a Schneider CD. Significant numbers were built, and shared the elongated running gear of the American Holt tractor as earlier employed on the Schneider CA1. It was considered a successful prime mover, and remained in service for many years.
A good number were sold to Japan who continued to build them under license. These vehicles were later encounter by allied troops in the Pacific theatre during WWII.
I did, but I don't. Many years ago I sold my WWII collection which included the fine Bellona booklets from the late 60s. One of them was Japanese Tanks; it had a number of pics. Another source was the old AFV News from the same period. I recall several issues with pics of these vehicles in various states of damage. George Bradford likely can tell you more ( he'll hate me for this)... Steve Zaloga is another knows-a-lot person who might be of help...., I think he occasionally lurks over at Missing-Lynx. Good luck....
It seems that although its called the Schnieder Tractor most were built by Renault. Schnieder designed it either before or possibly in parallel with the tank and didn't have enough capacity to build both so it got farmed out to Renault (see Ellis and Bishop - Transport of WW1)
