I thought it would be nice to fit a NOS Cyclo Olympic derailleur to this bike as it matched the period and I had a Bayliss Wiley Freehub with 1/8th cogs to match....
All I can say is DO NOT DO THIS... that way lies madness. The dearilleur is the most fiddly thingto set up I have ever met. It appears to have a capacity of 4 teeth which makes the 4th cog (22t) useless even though it can reach it horizontally.
It looks very cute but changes like a neglected combine harvester and hard to set up.... if I had any hair I would have lost it by now.....
