36 Colson flyer. I've had it about three years now, one of my favorite bicycles to ride and Colson's. When I got and the parts located after. The handlebar is not necessary Colson issued but indeed an early 36ish texashorn one which I really enjoy, has a very good feel when riding. The front fender had it original horn light hole patched up so I finally drilled it out and added the lite and added the long feather which is appropriate for a deluxe tall frame but it was from a girls bicycle so I had to drill the right additional ones as it is on a boys. Tough guard to come across. The rack however which is also a 35-36 tubular issued one for high end Colson in those years is nearly impossible to locate. It is missing a brace. Still a project in the works.
