Seen the pics on the home PC. Yep, can't see it as being anything apart from being the 70's
Smack bang in my era LOL
The frame has got all the bits it should have, long point lugs, cutouts, Cinelli MC style crown, braze ons.... and the world's best design of seat stay cluster
The cutouts either side of the front brake hole, the longer point on the lower lug of the head tube and the three slots in the BB were traits of Hayden Lugs but everybody did them.
It just lacks a little of the very final finishing touches for a truly "bespoke" frame. The lugs are a little thick as they should really be filed a little thinner, the rear dropouts have not been re-profiled as they should. If you are having it finished at a framebuilders I'd have the dropouts tidied as it would play on my mind
The Cranks are the obligatory Campag with Super-record chainrings and the headset is the killer EDCO which came with the Raleigh Professional 753.
All in all looks like a well made stock frame and would likely have carried a well known name. Fork rake and braze on's would make it a Road / Criterium / sunday summer club run bike with a midweek 25 TT thrown in.
I wonder if someone like EG Bates built it?
Standard 70's kit with a few scratches here and there isn't that expensive...........just stay away from NOS. AgentOrange's nuovo record rear mech NOS went for £67 quid. I picked up one with a few war wounds for £18
