Hi Cylord,
This is not a military musket but the remnants of a ca. 1760 East German or Polish wheel-lock short hunting rifle (German
Stutzen); the horn inlay in the stock might be original, then it's Silesian. Most probably though it's a 19th century 'embellishing' work.
The lock is of the plainest and latest form, with some elements missing from the left inside - see screw holes! The trigger is a crude replacement. As it is a rifle, it must have had a set trigger which is also missing now. The fore end is broken off, and so is the ramrod finial.
I would not even touch it, to be honest, but then, my fellow forum members know that my standards are strict and uncompromising. This does not have to be true for everybody - to each his own!
Best,
Michael
