I might add that your bike has unusual features. The fork has a non Raleigh standard headset, which happens on occasion. It could be your fork was old stock when Raleigh assembled it and therefore had the older British standard thread. Or the steerer was re-threaded at a later date. Not common but I once had a Nottingham Sports with a campy headset. The decals do look pre Raleigh but the rear mudguard stay location behind the axle is a Raleigh giveaway. That and the Raleigh stamped parts.
