To pick a nit, Jim:
"Reynolds has documentation of Peugeot using metric
(French thread) tubing in 1980 while using imperial (Swiss and British thread) and metric tubing in 1981."
should read:
"Reynolds has documentation of Peugeot using metric
(French and Swiss thread) tubing in 1980 while using imperial (British thread) and metric tubing in 1981."
i.e., Swiss is, of course, metric, not Imperial (which should probably be capitalized).
