Henry got it, the 222 rimmed for the small action Martini Cadet, difficult cartridge to locate in the USA.

Second cartridge is very uncommon and few would know about it. It is the German 5,6x61mm Vom Hofe, designed in 1937 and still used in custom rifles

third cartridge is the 244 H&H used for hunting in Scotland, developed after WW2

last is the German 5,6x57mm RWS which is just the 7,92 necked down to 5,6mm also made in a rimmed cartridge too
