Robert Held’s book “ The Age of Firearms “ is the single best reference for firearms and gunpowder development and use from their inception through the 1870’s.
The peripheral information included therein about warfare, politics, superstitions, human behavior, and the various social classes is fascinating and sometimes pretty funny. Possibly the most enjoyable book I have ever read. I still pull it out and read parts of it at times.
The book contains copies many period woodcuts and very high quality detailed drawings of the guns and related items. The detailed drawings were done by the author’s VERY skilled wife.
This book was the very first book on the subject matter I ever got. I was 13 years old at the time. (I am 68 now).
Copies are still available on the internet, surprisingly. Not very expensive either. I bought a spare in excellent condition for something like $18 or $23 or something like that. They are typically large, soft cover.
I cannot recommend this book highly enough.
