Another quick re-examination of the accepted wisdom. It's common for literature about the M1917 to state that it differed from the Renault in a number of respects, including a) a bulkhead was constructed between the engine and crews compartment, and b) the Renault engine was replaced with a 4-cylinder Buda with the addition of a self-starter.
However, I have recently read that experiments with a self-starter didn't begin until 1919. I've also been told that the FT did have a partition between the crew and engine compartments - maybe the M1917's was different in some way, but the FT seems to have had something.
"Sometimes things that are not true are included in Wikipedia. While at first glance that may appear like a very great problem for Wikipedia, in reality is it not. In fact, it's a good thing." - Wikipedia.
What you say about the self-starter is interesting, as you'll recall the discussion about this last year (perhaps?). It appeared to us then that the M1917 must have been provided with both electric start and socket(s) for a starting handle, which caused a bit of confusion - although as I said in that thread, it was early days for electric starting and vehicles would likely have retained a starting handle in case the electrics refused to work.
Unfortunately, whether or not a starting handle is present is unlikely to offer any hints as to whether electric start was fitted in 1918, or came along later. Must have a look at FTs.
TCT - thanks for those. There's clearly something there, but it's hard to tell exactly what. The AMMS pic seems to show some sort of perforation similar to that on the M1917. On the other hand, it looks crude enough to have been a bit of improvisation - rough holes cut in for bits of the engine to poke through. (Also a bit disappointing that Mr. Maloney describes it as the FT18). But Witold Lawrynowicz's phototour definitely shows something more organised; see photos 154, 158, & 160. The partition in the M1917 (pic 228 & 235) is different again.
Looking at these, and adding some info provided by the Weald Foundation, I'm beginning to think that there was a partition in both, but that in the FT it was several pieces bolted together in some way, whilst in the M1917 it was built in to the structure, if you follow me.
The starter: TCT - I can't find the earlier discussion; can you post a link? Ivor - yes, I am going off "Stuart". Witold's picture 244 shows the "instrument panel" with an "ignition switch" but no confirmation that it's a self-starter. What is pointed out is a coupler in the bulkhead behind the crew compartment for crank-starting the engine from inside. Hunnicut (p29) says that the M1917 did not have a self-starter, not even those completed after the War, just the extra coupler.
Sorry if this is old ground, TCT. Can't remember details of earlier discussion.
BUT another remarkable (at least, I think so) thing has emerged as a result of this digging, which I shall put in a separate thread.

Afaik the "ignition switch" earths the magneto. The wire from the magneto earth runs along the right side of the hull. Normally the engine would be turned over
James, I can't remember if there's much relevant in that thread from last year, but I'll have a look for it. In the meantime, did you think of looking on Landships II? I knew there was a technical section drawing there, which indeed seems to show a partition between compartments; I also found there are old pics taken by Peter Kempf, showing the interior of the Belgian Army Museum FT! It shows a definite bulkhead, different from the one in the Saumur FT, yet also lacking the intake grilles of the M1917:
we have come across evidence of the firewall in our own vehicle. If you look at the attached photo look at the top left and right. you will see where the firewall latches onto the frame. Also the Renault recruit training manual goes into some detail on the subject. A rough translation goes as follows:
Fire-protection: the crew positions are separated from the engine room by a fire wall made from sheet steel. Under normal circumstances the 2 shutters placed on each side of the fire wall are open to allow the ventilator to draw in fresh air to cool the radiator. In the event of fire, a button releases these 2 shutters which then seals the openings, and prevents smoke and flames invading the crew space, giving them time to escape.
