German company. Brand name used by "Füllhalter-Fabrik Gerlach & Bezner" based in Leipzig (LEIPZIG und Pardubitz). Active since at least the 40s (by letter of 12.10.1940 on Ebay). After the expropriation of J.Brod by the Nazi it took their production facilities. The activity ended with the transition to the nationalization of the company made in 1945, after the Soviet occupation when the adopted brand was Penco, but the brand "Imperial" survived until 1950 when it was completely eliminated from catalogs.
