Yet another mystery frame thread

Re:

Amazing, I never even clocked that hole on the hanger! Older than I thought so even harder to find out.

First thoughts were Holdsworth Mistral/Claud Butler Torino..... going on the rear drop-out, brake bridge, fork crown and wrap over stay.....
but, I’m not so sure about the head tube lugs and the number doesn’t work with Claud Butler (can’t comment on the Holdsworth numbering)

Re: Re:

Campagnolo Sport was a single roller gear with the parallel arms sprung from the top bronze casting. Used on many Italian commuters with close ratios.
I bought the last ones I could find in the UK in mid 50s.
By using the top sprung casting from the Sport on the standard GS we produced a far better gear change. Easy to tap out the alloy rivets and reuse them. Simplex held the patent for gears with sprung arm and roller cage, so Campagnolo couldn't do it.

Eeeh, every day's a school day! Didn't know the Sport was sprung, I always thought it was a naff alternative to a Gran Sport. Excellent tweak there Keith using the top casting. How many Sport mechs do you see these days?

BTW, I like the frame painted!

Ned, Sport gear didn't sell in UK because commuters used hub gears, until the NSU Quickly killed off the commuter bike manufacturers.
