I think no one better than him can provide us with the information we are looking for, or point us to the appropriate sources, and being an enthusiat himself, he could take an interest in our little project. What do you think?

His email address is: JCF@phares-de-france.com. My written French sucks, could you drop him a line explaining to him what we are doing and the information we are looking for?
