Jerry Moos asks "...How common were trple chainrings in the 50's and earlier, and how well did the typical rod FD's of the day handle a triple? ... What rod type FD's were used with triples in the 50's and earlier? ... Anyone have good photos or explanation of how to fit a Cyclo two-wire FD?..."

To add to Jan Heine's comments, here's some catalogue input.

Various Simplex catalogues from 1948 through the 1950s state the Simplex lever front derailleurs of various types are for double chainwheels, and there are no triple chainwheel cranksets listed in the catalogues.

Various 1950s Cyclo Benelux catalogues lists only double chainwheel sets, and state the Benelux lever front derailleur is for double chainwheels.

The 1952 Brown Brothers catalogue lists no triple chainwheel sets, and says the Huret lever front derailleur is for double chainwheels. I don't have a Huret catalogue to determine what Huret themselves say about their lever front derailleur.

A 1956 Simplex catalogue shows a cable-operated Juy-56 front derailleur and says it "...will operate with a triple chainwheel and as such is the only gear made today with such a feature." This catalogue does not list a triple chainwheel set, only doubles.

If Jerry meant a two wire Cycle RD and not FD, here's instructions:
