I believe that my Rapide is a Harpers rebuild, consisting of "B" upper and rear frames, Girdraulic forks, and a very, very early diecast engine. Even though the engine number has been restamped, the original number is still quite visible, and begins with 95xx, I do wonder exactly what month and year the factory first made the diecast cases...? The bike was ordered for a customer in the USA by Harry Belleville back in 1963. I have very little other info on the bike, but it appears like so many other ex- USA machines I have seen, to have had very little use, and even though it obviously doesn't have matching numbers, it is in remarkable condition and very original, as you might expect, it rides like a dream. Are there many other Harpers bikes out there....it seems to be a grey area, in the history of the machines. Cheers for now......Greg.
