Cheers for the additional info USAzorro, yeah with what my Dad can remember, it probably is a 60's model. Yeah, I'm not really restoring for a full on road/race bike, just so that its better than sat rusting in the garage, but I obviously want to do a fairly decent job. CravenMoarhead, just to clarify, the bolt on top that should be fairly long when fully withdrawn? Didn't realise that was how it was attached, Cheers for the advice!
