Hi, thanks all for your attention.
I'm renovating my unidentified 531 bike this spring/summer, some details below which I hope you may be able to help with because I've hit a brick wall:
Lugs are quite distinctive, but actually proved to be in fairly wide usage for a while. I've seen photos of many makes using the same, mostly 531 from as early as 1979 (Raleigh Track) through to mid 1990's (Graham Weigh) & including in between: Steve Goff, Keith Coppell, JF Wilson, Harry Hall, Nigel Dean, Bob Jackson & Ellis Briggs.
Can anyone help me narrowing down list according to serial no or even serial no format?
Serial no looks like 415 but paint is quite thick & there's small possibility it could be 4-digits. Also seems to be logo in diamond shape. If bike were upside down with front of bike to your left it would read horizontally near the top edge of bb.
I believe the bike spent its whole life in north of England before I took it down to Cornwall.
It has custom braze-on on top-tube for race no, braze-on for front mech, concealed rear brake cable, campag rear dropouts & chrome forks under that paint!
I don't think there's anything distinctive about bridges & seat stay caps can be seen in pics.
Thanks, Robert
PS - Decals needed only if positive i-d can be made.
