Your "Interarms" box has 1948-51 Sovietsurplus 7.62 Tokarev ammo in it...your decision on whether to call it 'Tokarev' or 'Mauser'. The Finnish
boxes are interesting. They are repacks of often captured Soviet or German
ammo, and sometimes contain pre-war 7.63 Mauser or early-war 7.62 Tokarev cartridges.
