Schlosser was a small car builder run by Eduard Schlosser, a furniture manufacturer from Drnholec, who built a passenger car around 1904. In June 1907 he took part, with Hans Ledwinka, designer at the NW car works in Kopřivnice, in a promotional drive to Jeseník held by the newly founded Moravian-Silesian Automobile Club (Mahrisch-Schlesischer Automobilclub).
