How old is your frame? 80s/90s? Almost certainly be a standard (68mm British thread) BB.
In my, fairly limited experience, Raleigh only used their threading on old (60s and earlier) three speed bikes.
As suggested above just measure the shell, even without callipers a difference of 5mm should be easy enough to see.
