[CR]83 Bob Jackson help.

Hi crew, I have just brought home a Bob Jackson with curly stays, Magnum Opus lugs and 50th group (low number) BB has 22083 and drop-outs are Columbus. To see pics, go to the Bob jackson album on http://au.pg.photos.yahoo.com/ph/gts753/my_photos . The bike has seen almost zero miles and paint, chrome, decals and running gear are perfect. I know there are Bob Jackson and Hetchins experts out there, either lurking or contributing. I intend keeping this bike and would like to know if anyone can enlighten me on its place in the plan of all things Bob Jackson. Such nice touches as the titanium cluster, leather stitched bar covering and the best available (at its time) group just makes me wonder if this was anything out of the ordinary. Many thanks in anticipation Greg Softley Coffs Harbour (check it on Google Earth) Australia
