Specialty books are great, I bought every one I could find on the subject of firearms back when I first started collecting ( anything that went bang) But you have to know the book exists in order to buy it, and back then information was not so easy to come by. It took me three years to figure out what my Swiss Vetterli rifle was, today with the internet I could find out in five minutes, best tool there ever was for the collector. I hope you can publish your book some day, I would love to read it. Every gun is collectable, show me the gun and I will show you someone who collects it, from Mossberg .22's to .32 pocket revolvers of the 1920's, I collect them all, next on my list is a Remington .31 steel frame revolver, I have been eyeing one for some time, and it will fit nice in the case with my Uberti 1849 Colt.
