I think research books are almost more important than the guns themselves, especially at the onset.
I, too, am interested very much, but only if it is not a "coffee table" book. I already have one of those that is relegated to the bottom of the stack of books I have.
How many pages in the book?
Dr. Jim L. Davis started a website many years ago called Replica Percussion Revolver Collectors Association
http://rprca.tripod.com/ which featured many photos of such revolvers. The problem with his site, IMO, is that he did not include manufacturer, date codes, importers, and other useful info concerning each gun pictured.
I hope yours is different, sir. Keep us informed, please.
Regards,
Jim
