Hello Rick ,
First , if somebody on the list has a firm idea of when your frame-set might have been made , I'm very curious to know how old it really is !
And , well , I don't have all the old Campagnolo catalogs . I keep INTENDING to place a big order with Chuck Schmidt , at Vélo - Rétro ( what is my problem ? - must stop procrastinating ! ) .
However , I can tell you that the French manufacturers definitely made just the item for which you are looking . Simplex & Huret made "clamp-on" or "band-on" shift levers , with , a left-hand shift lever attached to the band , and a hole on the right side to fit over a brazed-on lever boss .
I seem to almost remember Campagnolo made one , but I'm not 100% sure .
HOWEVER , I just HAVE to say - what a totally cool frame-set you have !!
Since we all seem to have several bicycles each . . . Hey Rick ! , if you already have a couple of "10-speeds" ( or much more ) , you might think about leaving this one without a front derailleur .
Just a thought .
And here's a more radical thought , if it has rear-facing , horizontal , rear-fork-ends , track-style . . . And if it has a single brazed-on shift-lever boss . . . I've read that a shift lever designed for a derailleur does a fine job of shifting a Sturmey Archer rear hub !!
I think I'd stick with a 3-Speed , and not try for a 4-Speed . And if a vintage AW , with a smooth chrome-plated shell , and a date stamp from long ago , just does not seem exotic enough . . . You could find a "vintage" Sturmey Archer hub with an ALUMINUM ( aluminium ) shell , like an AC ( close ratio ) , or an AM ( medium ratio ) , or even an AW ( wide ratio ) with an aluminum shell ( they did make a few ) . Of course , if you didn't mind spending the money , you could go with a fixed-gear 3-Speed Sturmey Archer ASC !!!
( I've read that you have to know what you are doing , if you try to shift an ASC with a non-ASC shift lever . It would be a shame to damage something so rare , and so expensive . So seek some expert advice first . )
Just a thought .
:^)
Congratulations on a very interesting frame-set !
