I looked at (& probably now own) a Dawes Atlantis. Of course, I have a few questions...But first pics:

It has Suntour Power shifters, Weinmann 605s, Sakae Super Custom crank, 105 rear derailleur, & Campy Omega Strada Hardox wheels.
I'm guessing the wheels & 7 speed Suntour freewheel are not original?
How do you tell what the hubs are? They Just say Campy & British 1370 x 24 tpi.
Any guess as to year? Did it come with 27s originally?
The serial number is stamped in the BB it is RC4854.
Thanks.
