In the last few years, Dove on-line has been expanded and we can filter on more types of towers (as well as other details) making it so much more useful. Is it defined anywhere (sorry if I have missed it!) what is included in some of the 'Ring Types' in particular 'Other bells' and 'Display bells'. These 2 lists seem to be rather limited short if we consider what bells may exist. Thanks
From the Dove’s guide homepage you can click through to more ‘about Dove’s guide’ and this says:
The following type of bell collections are currently in scope:
rings of three or more bells hung for full-circle English-style change ringing;
carillons in the British Isles;
bells weighing 40 cwt or more in the British Isles;
additional bells in the same location as a ring, carillon or 40 cwt bell given above; and
bells in buildings under the jurisdiction of the Church of England as part of its Church Heritage Record.
Future collection types will be added as part of future development.
So I think the only other bells and display bells are those in the same building as a set of bells for change ringing or carillon.
But the Dove’s team seem to be fairly responsive so you could contact them, directly for more clarification or to provide information about bells which could be included but are not yet.
