I presume this is a Perthus frame and forks, they tend to go for £200-250 depending on condition but that is in standard configuration with Shimano 600 rather than Campy kit. Given the history attached to this model, assuming you can prove the provenance beyond the name on the top tube then it should go for more than that, but how much more depends on the day. I would suggest you give it some TLC before you try and sell it as it will look a lot better cleaned up.
Thanks for the reply Brendan, this is Reynolds 753 tubing and Peugeot frame. With regard to provenance, I'm not sure how I could prove it, was bought through a casual friend at the time that I am no longer in touch with who came from the Milton Keynes area and who knew Paul. A friend of mine also bought a couple of Paul's old bikes, a Vitus that he had ridden when he was still competing as an amateur and another I can't recall. I would imagine that the decals and detailing would provide sufficient confidence. The brazed on lug for the race number on the top frame and as mentioned the wolber decals, campagnola equipped decals etc. Never saw these on a reproduction bike, but might be wrong? I am 100% that the bike is genuine, though in fairness I understand interested parties would want to be sure if the history of the bike was the appeal of it.
With regards tidying it up, I think it would deserve better than what I would be able to do and would be better off in the hands of someone who was skilled at this kind of work.
