George, thank you very much for the information; much more than I ever expected. I think knowing some of the history makes looking at and holding the gun a whole different experience.
I looked up the book you mentioned and found that on archive.org from the Cornell University Library are digital copies available in a number of formats; not the same as holding an actual book in hand, but an alternative. Here’s the link:

@Ed: Thanks for the interest but currently I’m not looking to sell and not sure if I ever will, but I will keep you in mind if I ever decide to. Only thing wrong I can find with the gun itself is a mismatched number on the rear toggle link, hoping to eventually locate a #85 to match. If you’re interested in seeing some photos you can visit one of my other threads here.
