Kind of a late reply here, but I have to wonder if this is indeed a c.1971 but not the Holdsworth Pro track frame but rather its clone - the Claud Butler International. Reason I wonder this is because the serial number does not follow any recognizeable Holdsworth pattern, but does fit for a '71 Claud. I have a 1968 Claud and in process of trying to make sense of its number I have deduced "Claud" Holdsworthy factory frames were given a distinct sequential numbering system from the "Holdsworth" frames during the period from 1966 to 1976.

The Holdsworth Pro and CB International track frames were essentially identical. Perhaps the original owner wanted a Pro and not the Claud version or perhaps at some point someone simply decided to call it what it really is. From pics it has less chrome than usual for 1971 but I believe from description in Kilgariff's catalog factory finish was to choice. Granted chrome did became "dear" by mid 70's and it would have been typical to have chrome just on dropouts by that point. Or perhaps some of deteriorating chrome was later painted over during a respray? In your photos is that perhaps chrome showing through under some of fork and stay scratches?
