Hi John, Its a BOB JACKSON
Had a look at your pals frame, and as a former framebuilder for Bob Jackson I'm going to state that I'm 99.9% sure its a Bob Jackson Olympus.........note the extended tangs on the bottom bracket shell...the heart shaped gear lever catch.......and yes we did the chainstay bridge that way!
The only thing which is slightly a miss is the use of a Wagner chevron top fork crown instead of the typical 14bis semi slope...with welded on tangs [fork liners]....but the fork on this bike also has fork liners, even so I'm still convinced its a BJ......it might even be one I made?......my own Olympus had a Wagner crown, but I didn't bother with the fork liners.
Wonder where my 1973 BJ Olympus is now!?........if anyone out there has a 23" x 22" top tube Olympus with a Davis sand cast BB shell with the extended tangs and unusually an extended tang underneath the bottom Prugnat type I headlug, and with a Wagner crown with the centre point removed, possibley still with half chrome front and rear stays [last seen in a French blue enamel, and sold to... I think... a Mr Guymer? in Hull UK] I'd love to be reunited with it again!
