I discovered that Campag and Stronglight chainwheels and cranks are not interchangeable on the same length axle.
Quite pleased with final outcome as I rode around the block to check that nothing came off. Still needs a shakedown ride - I bet something will need tightening.
Two pack (2K) lacquer seems to be an excellent product. Although it says use within a few hours I have found that the mixed life can be extended to nearly a week if stored alongside the milk bottles in the fridge.
I would still like to know the original frame builder. It wouldn't be difficult to print a decal and fit somewhere. In the
meantime "Nonloso".
