Lew et al - The Gustav Genschow Co. A.-G. was really an international company as early, at least, as the 1920s. They had offices in many cities in Germany, as well as some abroad. Their 1933 “Munitions-Preisliste” (Price List) shows catalogs available in German, English, French, Spanish, and Portuguese.
In that catalog, their primary address is Hamburg, but they show offices in Berlin, Köln, Königsberg i. Pr., Franfurt am Main, Nürnberg and Vienna. For some reason, the Argentine connection is not mentioned, although that dates from earlier than this price list. This catalog also shows “Waffen-Fabrik in Spandau.” I found that interesting in light of the fact that my earliest Geco box, the same as one lew shows, had Spandau-headstamped ammo in it from
November 1918. I don’t know if the two, the fact of Spandau surplus ammo in a Geco box, and the mention of a Spandau connection in the catalog, are related, however. It is only offered here as a matter of interest.
The 1934 Munitions Price List (Export Catalog) shows the main address of Geco as Berlin, not Hamburg, although Hamburg is still mentioned in the places where they had offices. However, the 1936 catalog reverts to the Hamburg address line as primary It also shows ammunition factories at both Durlach and in Wolfartsweier and actually shows it as the factory for Hunting Ammunition, Pistol cartridges, revolver cartridges, Flobert munitions, rimfire ammunition, paper cases (assume shotgun shells for reloading) and Sinoxid primers. Durlach is shown primary as a lead-shot manufacturer. They also show a leather factory in Altstadt-Hachenburg and an Arms factory in Berlin-Treptow.
I have a nice little 1940 Geco Calenddr and fact book titled "1940 Notizen für
Jäger und Schützen (1940 Notes for Hunters and Shooters). It reverts the main address back to Hamburg and also notes offices in Berlin, Frankfurt am Main, Köln am Rhin, Königsberg, Nürnberg, Vienna, Rio de Janeiro, Buenos Aires, and Santiago de Chile. Factories are shown at Durlach (ammunition and shot for hunting), Berlin-Tretow (Arms) and Hachenberg (leather wares). The Wolfartweier factory is not mentioned in this booklet.
I have a little two-page ammunition catalog in Portuguese, unfortunately not dated, that offers only the 6.35 mm Browning and 7.65 mm Browning cartridges. The company name on it is Sociedade Geco Limitada, Rua Theophilo Ottoni 35, Rio de Janeiro, Brasil.
Hope this is of some interest to those with an interest in Geco and its history.
