For anyone interested in Jäger (Jaeger) Rifles I highly recommend the book Steinschloss-Jägerbüchsen by Erhard Wolf and the Translation book by Eric A. Bye. The book is in German but the Translation book that is also available makes it a super resource. The main book with 570 pages has stunning photography of the highest order and lots of never seen before information.
Contact Jon Spencer of the German Gun Collectors Assoc. for information on price and availability. You can call him at (435)979-9723 or email him at: firstname.lastname@example.org.
First we open this archive page with a Slider of images from Herman Historica Auctions in Germany of a Johann Keuchenreuter – Jäger Rifle which they sold in their Oct. 27, 2016 Auction.
