A scan of the brochure for the Villiers two speed gear. Not a derailleur system as it is essentially a chain gearbox. An interesting dead-end in bicycle gear design. Puzzlingly complicated to fathom and rather heavy the Villiers two speed was a product of the thirties though when production was started and ceased exactly I am not sure.
