Retro Newbie
I am just doing a deep clean and rebuild of my Claud Butler bike which I bought (already renovated) from Bikes For Good Causes in Wood Green several years ago. If I remember correctly the bike had been sitting in storage in someones garage and was donated when they passed. The shop put some new parts on the bike (including chainset, pedals, freewheel and possibly wheels. I think they may have also resprayed it too. Either way they did a great job but it is time for another big clean up and I got curious about identifying the exact model of the frame if anyone here can help? I have found matching frame numbers (430
under the bottom bracket shell and on the steerer tube. Using the frame number guide on nkilgariff.com it seems like this four digit frame number could either be a 1938, 1964 or 1973 build. My guess would be the bike is more likely to be a sixties or seventies build? The shop told me it was Reynolds 531 and it has the sticker which I assume was faithfully replaced.
Looking at the 1964 catalogue of R531 bikes and trying to inspect the detail on head tube I can't seem to find a match. This suggested perhaps it was a 73 frame (these seem to be listed as "custom" on the frame number guide) but there is no catalogue on nkilgariff.com. I looked at the 72 catalogue and searched those bikes online but couldn't find anything that looked exactly like it.
I have attached some pictures. Let me know if there is anymore details/photos that would be helpful.
