Otto Eberhardt Patronenfabrik was a munitions company established in 1860. The company's Hirtenberger Patronen, Zündhütchen und Metallwarenfabrik near Wiener Neustadt used forced labor during World War II from a sub-camp of the Mauthausen-Gusen concentration camp and produced ammunition including 9×19mm Parabellum and 8 mm Mauser cartridges. The company also had a factory in Ronsdorf near Wuppertal which produced rifles. Additional Gustloff facilities were in Meiningen and Weimar.
