Kurtis, here are some photos of the P-59 box. The one on top is the most interesting one.
Kurtis, the markings on the boxes. Only the dates differ.
The box was painted black by the original owner who removed it from an ammo train, Guess what was in it?
This is how they fit in the box and they are heavy as hell. You would have had to be in good shape to slug these all day.
Kurtis, here is the last one. This is the tag that was in the bottom. Interesting that a farm machinery company made these.
Cheers,
Barry
