There is a difference between Bells and Bellsets. A Bell consists of a bell ringer mechanism only and this may be an open type bell or enclosed within a case.  A Bellset consists of a bell ringer mechanism plus addition items of equipment (could be anything from a relay to capacitors and can include switches).

The diagrams for Bell, Bellsets, Buzzers and hooters are in the N500 - N599 range.  In general, prefix a Bellset number with 5 to find the wiring diagram number e.g. Bellset No 48 is diagram N548.
