To me it looks like a very late 70's because of the rims arn't the ones Raleigh used for some time, they stopped around 1980, could be a mongrel though Though I havn't seen one of that year thats made in england, but that may depend on where the bike was actualy made, maybe in late 70's it actualy was made in england, ones like that here don't have that stamp only early up to 1976 maybe. should tke more pics
