Isn't there an annual race somewhere in France with vintage machines and the riders in vintage kit?
As for the fixed versus freewheel debate in pre war tours I've often wondered about the quote attributed to Desgrange in 1902, he apparently said "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailleur? We are getting soft...As for me, give me a fixed gear!" But of course he would have said it in French. I know that fixed wheel fashion victims (sorry fans) like to trip out this quote as if it were gospel, but I'm not so sure he meant what the fixie crowd think he meant. Notice he speaks of "variable gears" in that context does "fixed gear" just mean "not-variable gear" rather than "fixed wheel"?
What was the terminology like back in 1902? The word freewheel is after all used as opposed to fixed wheel, not fixed gear. A fixed wheel is something has no freewheel, but is can have variable gears. However I suspect that Desgrange used the phrase "fixed gear" to mean what we would call single speed.
