I reckon the two groups I follow that would relate to this subforum are

http://www.flickr.com/groups/oldcycles_/

and not as much vintage action of course, but still a great group:

http://www.flickr.com/groups/steelbikes/

And yes even with moderation they are a scattered conglomeration of pics. But often if you see a bike you like, glance to the right and see that there's a set of pics that contains the pic. Click on the Set's link and you'll see a more cohesive set of pics that that pic is part of. For instance here's a Merckx in the old bike group and the page contains a link to the set Eddy Merckx Kessels (Set: 21).

The number in the parentheses indicates how many pics there are in the set.
