Jim, John,

there were several rifled muskets of different German states in use during the CW. My mail of 17th related to the term "Suhl rifle". The following guns are rifled "German" muskets:
Badenian M 1816/40/52, put together from parts of French type M 1816 flintlocks in the St. Blasien armory (Black Forest), some with French lockplate marks (St. Etienne etc.), some stamped "St. Blasien" (these with rounded percussion lockplate), Minié type rear sight or fix rearsight, 17,5 mm (gun often wrongly classified as Wuerttemberg!), unique hammer form.
Prussian M 1809/55 (conv. from flintlock & rifled) and 1839/55 (rifled), adjustable rear sight, marked Potsdam, Neisse, Saarn, Danzig, Suhl, 18-18,5mm
Bavarian M 1842 with large "ellbow" rearsight,typical Bavarian club type cherry stock, mostly unmarked, some Amberg, 17,8mm.
Saxon RM as told in my first email.
It is also quite possible that few of the Prussian M 1835 Jaeger rifles, (flintl. conv. to perc."à tige"), folding rear sight, cal. 15,5mm, mostly Saarn stamped, found their way to America.
You see there is a large variety of guns that could be named "German rifles". Only the Saxon model was first class and with .58 even superior to the .54 Lorenz but perhaps a bit clumsier when I take a look to my both collection pieces. The Saxon can also by a soldier not easily been identified as a German gun because most of them were marked "Malherbe, Liege" and have with their French type back action lock not a "German look".
Best regards, Marc
