Custom lugged steel frame with top quality components for the job. Probably a randonneur. If I spent that kind of dough on a similar C&V I'd probably limit my ride time on it because the cost of maintenance (with equivalent quality, original spec NOS stuff) would be a lifelong issue, with higher cost and lower availability as the years pass.

I'd say my cap on a C&V would be $2k, max, versus the $5-7k for a top custom (the way I'd want it). $5-7k gets me a C&V bike I'd be hesitant to ride.
