Thanks, Raimey.
1897?? That's a surprise. Can you identify the Crown/S Crown/U & Crown/W
and the little figure with large boots and a club(?) ? Also, is this a Prussian gun?
I see no "prussian" in evidence.
These marks are under the receiver. Under the Bbls : Crown/S, eagle, 61xxx,
207M, Nicht für kugel, papp.16, V, and 65.4,75S.P.28,5BL, W
All greek to me.
Gun has side plates and fully engraved by Ad. Loesche.

Appreciate any further info Raimey, or anyone knowledgeable.
Thanks!
