Thanks Gerd. I just about blew that one. I had convinced myself that this was a shaft drive vehicle, and because of this had ruled out Truffault very early on. Because I was running out of possibilities, I went back and restudied your photograph. Doing so, I discovered that what I had thought was a drive shaft was apparently a structural member, and what I thought was a structural brace was really part of the belt drive cited in my Truffault reference. Anyway, what originally seemed like a relatively easy puzzle, due to the unusual suspension, turned out to be a bit of a killer.
