Hi Jack, I know that Pyro did the 1907 car and Minicraft did the 1906 (I have both) and they are pretty close to what you need, try ebay they come up from time to time, I think I paid about $15.oo plus post. The only drawback is that they are in 1/32nd scale, not a huge issue, but you may run into trouble with figures, Scale link do figures and a couple of others, it depends on what you want to do and how you want to present it.
I have never seen the resin kit...although I would like to now !
HTH. Regards, David. (do you have enough images of the preserved vehicle in Paris ?)
