A friend has two falcon road bikes, One is a powder blue mid 1970's Falcon Professional with 531 tubing and Shimano Crane drivetrain. It needs renovation, wondering what is it's worth as is (now BB, cassette, wheels req) and renovated. The detailing is astonishing.
The other bike is also a Falcon, with a derailleur marked Elan, defo not 531 and nowhere near the same standard.
Where is the best place to get a price, or do we resort to Ebay (where nothing similar seems to sell)
