JRJ Bob Jackson serial numbers/dating

futuristicoldman · Aug 19, 2015

Hello chaps
Can anybody here offer me any help dating my JRJ (early Bob Jackson). I believe it dates back to the late 50's but i'm not 100% sure about that. Her serial is 4680, she is sporting Campagnolo dropouts and nervex lugs. Any help or advice would be most appreciated.
Thanks

With that frame number it will be about 1963. See attached graph and BJ form taken off another post.
