Beautiful! I have a late 70's Condor lugged track and the quality is the best I've seen in person. Superbly filed lugs with nice cutouts, nothing too fancy tho. Rides like a dream. (think I need to build it up again...)
You could send Condor an email and see if they can date it for you. Usually all they need is the serial no.

And I'm gonna kick ImOnCrank's arse if he does indeed sell that Condor stateside!
