Holdsworthy made these in the early 70's, they owned the Claud Butler name also, but used it for mid range frames. This was the top model, and also supply to the trade for own transfers.

Lovely, thank you both. Do you know if it would have been sold as a complete bike, or just a frame+fork? I know next to nothing about road bikes so if it was in a catalogue somewhere I’d have some idea of what parts to look for.
I’d better do some research then, if I decide to rebuild it I’d like to get parts from the correct period. Top model = top parts then I guess. Any idea on the forks? I also googled Barrie Farnsworth but found nothing.
