I am pretty much sure most would be uninterested in either
I do depend on RSC or "Roman Silver Coins" for work with my coin business.
There is a space for a book on bells that would have this status.
If you are a technical writer, and have specific knowledge of bells, you could start the book I have been looking for.
If you have very specific knowledge of bells that is not possessed by others, you may want to put together a "Project" to produce a reference guide.
In my limited experience, I have found money available for two types of projects.
1. I am an expert on this specific product that no one else has produced a guide for, but need a tech writer.
2. I am an expert and I am also a good enough writer to go directly to an editor.
(BTW if anyone knows of a real reference book on bells I would appreciate the info. No show and tell books, real reference books seem to be in short supply).
