I want to buy a clean Cyclo Benelux Tourist derailleur. I'm in the process of returning my 1958 Holdsworth to the original parts. Shortly after buying the bike, I swapped out the derailleurs for Campagnolo Gran Sport. Since I'm using 32-46 rings, the earlier Cyclo Mark VII does not work with a 14 tooth difference. I'm hoping one of our British CR members can help. Please contact me off list.
