>>1858133I've found next to nothing about the frame on the internets, just one website that says
>Cicli Castiglione was started in the mid 1970s by ex professional road racer Luigi Castiglione in Palermo Sicily. His frames are recognisable by the hand made frame fittings, heavily modified fork crown and shaped cut-outs in the lugs and bottom bracket shell. Drop outs, cable guides, stops and lever bosses were all made in house by LuigiAnd a bike that's from '81 and has horizontal dropouts. Mine has modern dropout design, intermal cable routing and recessed brake mounts, so maybe it's a later model? Dunno. If the groupset is original maybe it gives us a lower limit for it's age.
It has a serial number as its only identifier.
