I imagine its one of the frames that Holdsworth used to distribute – the same frames went out badged as Holdsworth, F H Grubb, Bertin etc
Parts look roughly right for the time; TA cranks and rings, GB brakes, Atom hubs, Huret gears. (Gears may have been later, the original ones might have been Simplex, plastic rear mech)
Are the wheels 27″ or 700c?
Not sure it’s worth a respray, the original decals are the main redeeming feature.
It’ll weigh a ton and ride like a brick, but that’s the price for authenticity.
As ever, RetroBike[/url] is the place for people who really know about this stuff.
