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