IIRC the Le Mans 24h has ALWAYS been ACO and hence why it's got it's own regulations and often in conflict with FIA/FISA ones Will do some research in the museum.
btw ... re betting .... I checked and the UK based ones won't be putting odds up for anotehr 2-3 weeks. bet365.com have confirmed this with me. If I get time, I'll look around the French car forums and sites and see if I can find any over there.
