I have a spotless Raleigh Grand Prix from the 1970s. It looks exactly like a bike I saw in the 1974 catalog on Sheldon Brown's site but I understand that the bikes looked the same for several years. Is there a way I can confirm the year using the serial number?
A few details: lugged frame, cottered cranks, Weinmann centerpull brakes, Simplex rear der. Made in Holland.
