History note

Tiny cartridge intended for indoor target practice. This identification is tentative. The dimensions are very close, but the 4 mm rimfire/centrefire GECO is a rare round, and this ICI cartridge does not appear in available references. It is definitely not a 4 mm M20 Ubungsmunition cartridge: the rim of the ICI cartridge is of conventional rimfire form, and the case is 1 mm larger at the head than the M20.
