That dose look like a good book,

I think a joint collaboration of a few collectos could bring fourth a very good comprehensive book on the subject. Johnson had other collectors doing chapters in his series. Also there is no such thing as to many on one thing with new up to date info. Look at how may books on lugers and daggers for example.
A good chapter on knots/portepee in color would be great to and help ID some of the odd ones that can look close like the Justice and fireman. Fonts on RFV's seem to have two styles and some were plated and most were Polish. We also have DRP's, HVA's and police style marked KS98's, and grip cyphers.

We all could throw out some ideas an many of you guys have some killer examples to photograph and contribute. Maybe Terry could add the known seen TM with pics. Billy and Terry could add a lot to fireman chapter. We have Geroge, Houston, Andy, Wayne, and many others here that have a ton of info.

Just thought I'd add to the idea,
Steve,
