Hi group, I have a Flyer frame set that is numbered N 4133. I take this to equate to roughly 1965-66. There are no origional components with the frame that would help pin things down. However the Campagnolo hanger side rear dropout has the small hole typical of fairly early production. Anyone else out there with an N prefix frame ? N doesn't seem to show up on any of the date charts, but I would imagine it must be from just before the re use of A prefix. Thanks Greg
