This looks like a dead forum, but I found it because I just bought a mint 1989 205 GTi 1.9. In 2016 I built from scratch the 1964 Tour de France PX10 ridden by Tommy Simpson (not the fateful Tour). Here is the database of parts, I have since changed parts to be even more period, like a simplex seat post, delrin derailleur, etc.
In the last year I also bought a new old stock Comete. It is a beautiful bike. Here are pictures of both.
