First of all Charles, I agree the photo’s are a bit small but the QR lever denotes the origin. As for the drilling, it’s serves to be referential. I remember the 70’s Holdsworth’s and so forth that had drilled out components, most of which had been done by the owners. It was often less than perfect but none the less - signified the commitment of the rider. Club meetings that took place on wet windy evenings on country B-roads – the traditional British Ten. I may be nostalgic, but this is the classic and vintage page - isn’t it all referentialism to a by-gone era?

John, I think you are absolutely right about cranks and callipers – which is why I’ve been modest with drilling, it’s mostly countersinking. I’m glad you agree about the quality of the brakes – the crux of my comments. Dead cheap on e-bay.

Here’s a ring I made earlier (bolts are temporary).
