Sorry, Allan, but Targhediferro got in very quickly there. The point is his because I would have locked it for him to complete the puzzle, and we all know he knew what I was looking for.
Yes, it is indeed a Contal Mototri from about 1905/06. And I reckon the claim to fame is a good one, even if the vehicle itself was a complete failure during the event. They must have been VERY optimistic, or simply did not do an adequate pre-race survey. The car was abandoned in the Gobi desert, and I think there's a chance it's still there to this day. I just looked up the Wiki entry for the race, and apparently there were 40 entries, but just 5 cars turned up at the start. It's a fascinating story, what with the shenanigans of Charles Goddard and his Spyker.
