Do pleasure us with some fotos of the >>Pop-Up<< sight. Interesting novel addition of the hook on the trigger-guard-bow.

It is more than likely of Germanic origin, a Büshflinte-Sorte, Cape-Gun on a Casimir Lefaucheux Platform. More than likely made in Zella Sankt Blasii - Mehlis or possibly Suhl. Probably a 10mm BPE variety.
