The Kaufman book is a very good starting place for anyone wanting to find knowledge on the Pa. Ky Rifle. It would he;p us to suggest other avenues , if we knew what your goals were in M/ling.. There are perhaps 20 + picture books specifically written on m/l longrifles, Jaeger rifles , and transition guns from early to later. All are beneficial for a knowledge base. Start somewhere , be patient , and read all about the subject you can find. Been doing this 50 + years , and still have barely seen half of the info. It's a shame , 41 yrs. working in Electro-mechanical engineering , have to interrupt the important work , of becoming immersed in 18th century guns and history. What a shame we have to earn a living , and only study m/l history on the side. .............
You're on the right track.............oldwoodII
