Cyclo in France introduced 5-speed derailleurs in the late 1930s, I believe. This was their standard 2-wire model. Certainly the 1946 Herse tandem we used in Paris-Brest-Paris 2003 was equipped with a 5-speed.

and scroll half-way down. Further down is a 1952 Rene Herse with 5-speed Cyclo. That one even says "5 vitesses" on it.

The bike on the cover of our book "The Golden Age of Handbuilt Bicycles" also has the Cyclo 5-speed derailleur - it's from 1952 as well. And it wasn't only Herse who used them.

Later, Cyclo even offered a 6-speed model, which usually was used with a 5-speed freewheel and chainrest.

I don't know whether any of those ever were made available in the UK. -- Jan Heine Editor/Publisher Vintage Bicycle Quarterly c/o Il Vecchio Bicycles 140 Lakeside Ave, Ste. C Seattle WA 98122 http://www.vintagebicyclepress.com
