This is a 1980 model with earlier Borrani 4777 rims, 259mm rear rotor, IMOLA tank, short seat and paint colours ala 1975 750SS but with brake calipers from most likely a late Darmah, SSD or F1. Front forks are newer style Marzocchi with the fork caps that look like the Ceriani style but with the air bleed screws ala late MHR/S2 etc. Maybe the single bleed F08 Brembo brakes are from one of those bikes as well..... Should be a fun project to get underway soon.
