I'm 99.9% certain its a Bob Jackson 'Olymiad'
Note the extended tangs on the bracket, a feature on Olympus......but they usually had semi wrapover stay tops, and a semi slope 14bis crown with fork tangs [liners] welded on the crown.
The 'Olympiad' model which had the full slope crown and fastback on the side seat stays.....as this frame has. The hand cut heart shaped gear lever catch is another give away........
However, I think this frame dates from after my time working as a framebuilder at BJ's [71 ~ 76] going by the drilled tangs.......but then again.......maybe we were using the pre-drilled fork liners as tangs for the bracket shells?.......its a long time ago!
Hope this is of help.........
