If you can find this one at a reasonable price . . .Calligraphic Flourishing by Bill Hildebrandt
I just love this book. It is mostly flourishing with a broad edge pen but all of the principles are very applicable to pointed pen as well. He does have quite a few examples with pointed pen including a few by Michael Sull, Jean Larcher, and Raphael Boguslav. He also has a very detailed chapter on Cadel flourishes.
The cheapest copy at Amazon right now is $69 but you may be able to find copies through Abe Books, Bookfinder, etc. I lucked out and found a copy at my local Half Price Books for $8.
