I suspect that the main tubes would have been 753, the seat tube 531, the chain stays 531 and seat stays 653 or 531. btu it varied rider to rider bike for bike. dependign on what he was buidlign for. I have to be carful as i did not want to brazes up old 753 tubes as that is for masters only! very happy withthe out come and happy that sinnerman will look after her.
