Just showed it to a guy I work with who's really into track bikes but is one of the original OGs - he rode from Portsmouth to Cornwall in a aday on a singlespeed in the 50s and is in the process of restoring a semi lugged Claude Butler. He's loving the bike too and pointed out to me that there are some Holdsworth head badges on ebay, although I'm guessing that you want to ride this now rather than mess with the paint job!
