I was trying to decide between 1959 and 1963. Can't see whether it is unit construction. Looks to have the fuller front fender. Not 100% sure.
Harley something-Glide, authentic 50's would be Hydra or Duo.

Unit construction Triumph, 500? 650? NZcarnerd knows old Triumphs.....
Definitely a unit construction 650 but....those fenders look odd. I guess it started life as a TR6C?
