During the 1970's you could buy from our wholesaler's Italian made 531 racing and touring frames in bare metal. These were very well made and cheap. Many of our famous top makes purchased these and had them painted and transfered up as theirs. Typical Italian styled frames of the day which were fashionable back then. The frame builders I knew said it would cost them double the wholesale price to make a same spec frame with spear-point lugs and the same tubing and ends.
Thats all for now. Keep those wheels spinning, in your memories if not still on the road. Be lucky Mick Butler Huntingdon UK.
