Can anyone help me identify this Holdsworth bicycle. From what I have been able to determine, not much, but it could be a Mistral, a Professional or a cyclone or some of each or none at all! It is finished in team racing colours orange and blue, Weinmann centrepull brakes a GB stem, Brooks B5N saddle(covered in duck tape sorry!), 5-speed Campag gear. The forks seem to be square shouldered rather than sloping(this has thrown me as nearly everywhere says they should be Italian sloping crown and this one isn't) Further from the limited research I have been able to do so far, I place this frame somewhere between 1966- 1974 (It has a metal head badge).
Now the problem is, I don't have a frame number (not helpful) I am in Mexico and the bike etc is with my son in UK. I will try to obtain the frame number, not easy as my son is very busy at the moment.
I have enclosed some pics of the bike to help with identification, I hope they are OK!!
