I ran across some info on the firm of Heinrich Munch of Aachen, which was the source of the Munch Anson Drilling and probably the brainchild of Friedrich Munch, son of Heinrich Munch. The Munch Drilling was an adaptation and refined design of Ernst Kerner, which can be identified by a screw, or 2 screws, at the top rear of the reciever and being a tell tale sign. This screw holds the scear and allows it to mate with the top of the hammer.
Note the screw at the top rear portion of your combo and if you ever have it apart, I'd like to see a pic of the components if it differs from the above. Freidrich Munch evidently had a strong relationship with Josef Hambrusch of Ferlach and sourced his longarms and/or components from Josef Hambrusch. On your forend, there should a series of numbers with the number "22" preceeding the serial number. The frame with the pipe looking frame reinforcement makes one think of Merkel as does the scalloped frame, which I think is included to breakup the lines of the action and make it seem smaller than it actually is. They can take a larger robust frame and make it appear smaller. On any Austrian/Bohemian/German gun, a frame attribute has eye appeal as well as a true essential function, being a function form. But Freidrich Munch was an expert on breech technology, and probably multibarrel longarms overall. He had big dreams and wanted to corner the drilling market including double rifle drillings but the ideas and firm dissolved with his passing. The rifle tube and lugs were forged from one piece; therefore, I don't think you'll find an example by Munch with hammer forged rifled tube. But otherwise the firm Heinrich Munch seems to have propagated the basic ideas of pre-WWII Suhl drilings with their own advances in technology. Although he may have been a firearms merchant in later years, he was a designer as well as a master gunsmith.
Kind Regards,
