I think that's a safe assumption, but you never quite know with Raleigh. I wouldn't be surprised if a couple of thousand Grand Prix frames went through the wrong line at one point and ended up with BSC threaded bottom brackets and someone out there will say, "But my 1968 Grand Prix has an English-threaded bottom bracket!"
