Thanks everyone for all the excellent and informed comments here about my bike. Apologies for not replying but I'm on vacation, but will get to the bike once I return and answer all the questions raised. I've been holding off purchasing original parts until I'm a little sure of the period it's from. I know you can't be totally sure of course with the Cinelli, especially given some of the issues raised above.

I'm not massively experienced with restoring a vintage bike, but I do have a local coop nearby which should be useful and I can buy some of the tools recommended above.

If it means anything to anyone, I plan to cycle the roads of Foxrock in Dublin this weekend in honor of Samuel Beckett, a keen cyclist, who wrote a lot about bikes in his fiction.

Best

Pat
