Thanks for the help, so far!
A couple more pics. The bike builder first looked at the chain stay indents and he and the other shop owner agreed that the indents looked like Columbus. The steerer does not have a dove, so I'm not sure what it is. The numbers that are stamped on the BB are also stamped on the steerer tube. When I set the bike up with wheels, the head angle, while still steep, was not as severe as pictured previously. Total weight of the frame and fork is 6.1 lbs.
