He sold me the frame, and what I know about the frame as it is comes from him.
Does the drive side DO have porta catena holes? I would say 1982 or later...
The recessed brake mounting, along with under the BB cable routing and 80s 531 decal all point to a later date. Not that I know what much... Just from looking around after I got mine and from what I think I have learned.... mine is an 81... as butterfly bridge and over the BB cable routing... which are all older features and it has the 531 on an angle decal.
