Re: Wischo Model 11
If you post clear pictures, front and sides, including clear pictures of the grips and markings some one might be able to made a visual identification of it. You might also inspect it for proof markings. Every European country has a national proof law and Proof House, ( no, the U.S. does not.) That will give you a head start on the country of origin. Wischo was a importer and exporter, which means he also exported to the U.S., German, French and Spanish firearms.
