This cartridge is listed in Erlmeier, Brandt as an unknown cartridge for an experimental Austrian gastight type revolver. In Mötz and Kohlmann Vol.3 p. 146 it is however listed as the 8mm Pieper II revolver with Roth #482. As reference it will keep the listing separate, but for all intents and purposes it is the same as the standard Pieper design. This cartridge is also featured as such in Mötz Vol.1 p.201. (Erlmeier, Brandt Ref. 96A).
