Good catch on the stay/blade end treatments, thanks. The different dropout manufacturers was a big indicator, but this pretty much confirms the fork and frame didn’t start off together.
To identify the frame, we have cinelli BB shell and scalloped stay caps, old enough to lack bottle cage mounts on seat tube but new enough for TT cable guides and recessed rear brake mount.
Centurion was an adopter of vertical dropouts earlier than the other Japanese makes. Cinelli BB shell was not uncommon on early 80s Treks, but I’m thrown off by the scalloped seat stay caps.
