Sadly, to me since the publication of "Steinschloss-Fagerbuchsen" came out 8 or 9 years ago, our current active ALR membership have taken little interest in the work of the old Germanic gunsmiths. This is a must have book along with the English translation, if you desire to learn all you can regarding where the American longrifle originated. As for my other favored books on this subject, Kindig's book is top's because he goes into as much detail on the known information about the individual gunsmiths, along with pictures from his vast collection. Most of these rifles are true works of art and unfortunately out of reach for the man of average means to put their hands on. There is one more book that I think should be in everyone of our groups library. That is Ned Robert's "Muzzle Loading Cap Lock Rifle". His views on our favorite subject are truly ageless! Pictures not the best, but the reading will entertain you for many long winter nights.
