F10. A bit of triva for you, following on from my last answer.
With the German ammo cans without the insert's inside. The belts were laid in 250 rounds one way. & another 250 rounds 180 degrees the opposite way.
This got round the rounds being 'tilted' backwards with a full can.
The Postwar Tins were not as wide as the wartime versions. & also had a diagonal 'stripe' impressed from the inside, to stiffen the thinner steel material.
They also have the N.A.T.O Stock number impressed in the lid.
