The Robert Larsen Company manufactured a very small number of holsters from "Ersatz" materials for the Hi-Power. One example noted is marked "ROBERT LARSEN", over "BERLIN SW68", all over "1941". It is a black pebble grained holster with a tip similar to that of the Radom holster, and has a pull down closure strap. It is similar in style to a breakaway type holster except that the holster is one piece in this area. Although the Robert Larsen Company dedicated most of its production to the needs of the German police, this holster was for the commercial market.
The Larsen marked holster is dated 1941 and was certainly made to carry one of the many thousands of Hi-Powers seized by the Germans after the Belgian surrender.
