Malcolm Bull's Calderdale companion (just type it in)would seem to me to be the best help. Some - such as Shore Baptist Chapel - were still in use then, I know. I'm pretty sure Christ Church would still be in use then, but don't think there are many spaces anywhere now. Mankinholes / Lumbutts, up above Todmorden on the way to Hebden Bridge is currently being discussed with a view to redevelopment, I think, so get in quick, just in case - although I think that may be mainly non-conformist, I suspect for some time it's taken more than those.
