Peter,
Several years ago I bought a Holdsworth on eBay that was billed as "an older model or one off" professional. The seller extensively quoted information from Norman Kilgariff's Holdsworth site.

After much research I've figured that it's a WF Holdsworth "Competizione" model in orange and blue "Professional" kit. It's described as being "Built with good quality tubing" what ever that means. Also there's no Reynolds stickers but as I understand, Holdsworth et al. didn't use the transfers on their bikes built for the domestic UK market. There's no chrome, no Professional decal on the top tube, no fancy painting on the seatstay caps and so on. It weighs a ton!

The seller cited this 1969 Professional as an example of bike without the standard features.

I bought it with the suspicion that it wasn't a real Holdsworth Professional because parted out (if I ever decided to do that) the components on the bike were worth far more than I paid for it.
Last year I got a REAL 1972 Holdsworth Professional frame with all of the classic features. A major difference in workmanship plus it feels at least a Lb. lighter than the other frame.
