Hello guys. I need informations about ammo box from photos. It includes moving roller for heavy ammo belt. It has proper size for mg 151 /20 ammo belt but i didn't find any information to confirm that . There are no stamps but closure is very similar to one used in ammo box for MG 34-42 Pz 34 ( used in bunkers ) . Dimensions : 42 cm x 41 cm x 16 cm .
