Totally off the subject with the only connection being that of being a firearms merchant in Berlin, but
Büchsenmacher Paul & Anggelika Kleszczewski/Kleszewski of Berlin advertised as having a factory when in reality all Paul had was 2 foot powered lathes in the small basement(7m X 27m) of their home. The Verband Deutscher Büchsenmacher took his license for unfair advertising by allowed Paul's wife to continue. Too, Paul was a Hungarian in Berlin that survived for quite some time. A good read on Dietrich's website where the most astute custodian Larry Schuknecht maintains quite a depth of German info on the website.
