I run a website sharing information and photos of Tank Data Plates including the WW1 period. Data Plates were the plates fitted to tanks contain manufacturing info, serial numbers, dates and builder of the Tank. If anyone has any photos, information or questions please comment.
Attached is two examples plates, one is American Model 1917A Tank Plate and the other is a French Schneider CA Tank Plate. Any more information about these particular tanks would be great too.
What strikes me immediately is that the Schneider plate lists the type as 'CA.' I've never been convinced that the official nomenclature of the Schneider was 'CA1.' It's always seemed more likely that Schneider would have followed Renault's practice of using a two-letter job number. Things can then only become '1' retrospectively when it's necessary to distinguish them from '2' - Mark I tank, World War I, and Schneider CA2, 3, and 4.
On the other hand, the Van Dorn one is a bit of a poser. The model number seems to be '1917 A,' which I haven't come across before. (I don't think it can be the 'M1917 A1')

Its very interesting you mention that as while researching the plate i came across this information from the tanks wikipedia page under the designation section. https://en.wikipedia.org/wiki/Schneider_CA1
"Whereas the first order spoke of tracteurs Estienne, the factory designation of the tank was Schneider CA ....... This would seem to indicate that the CA suffix was merely a Schneider product code similar to those used by Renault. At the end of 1916, the type was called Schneider CA 1 to make a distinction with a derived tank project, the Schneider CA 2.
It makes sense as you say the until there is a later model you wouldn't have 1 at the end.
"Van Dorn continued post war production of the M1917 6 Ton" which matches the date on this plate and model of vehicle on this plate. The tank itself was known as the six ton special tractor in development. The Plate itself matches the design and information which should be featured on this plate based of experience with similar plates. The plate itself was purchased from Canada where a lot of the tanks were sold to and used as training tanks
Data plates often contain designations for vehicles as they were known in either pre production or by the tank builder. So the fact that the 1 is missing doesn't strike me as particularly odd. Do you have any other information apart from the fact that the Model 1917A part is missing a 1 to imply it is a poser?

Perhaps I didn't explain properly. What I meant was that the vehicle was initially called the 6 Ton Special Tractor and was designated M1917 when it entered service. I hadn't seen the designation Model 1917 A before. By 'poser' I meant that it was a puzzle to me.
