Larry,
I have a Carlton Flyer road bike as well (25") that I purchased from the original owner about 5 years ago. The Campy hub lock nuts are dated 63, although the owner thought he bought it in 65. Still cleaning up some excess patina, and just got a nicely used B-17 for it (thanks, Tom!). It has a Los Angeles bike license on the seat tube that expired in 67.
Cheers,
Mark Ritz
