Well, don't everybody scream at once about selling their surplus english-threaded nuovo record headsets ...

What is the closest thing to a "period correct" headset for a 1970's bike, that can be bought NEW today ?? What about :

(a) Stronglight A9 ? When did these begin production? (b) Chris King w/o advertising (custom ordered at a bike shop) ?

The headset I'm looking for would go onto an English 531 bicycle with mostly Campagnolo components. Does anybody know in what year this campagnolo chorus headset (from wwcyclery) was introduced? And where can I find answers to questions like these so I don't have to bother list members?
