At the 'historical' section of the NRA Convention, first floor, they had a John Browning exhibit, including a rig for the M1917 water cooled machine gun.
It had a brace of ammo on the carriage that were interesting. Including vintage ammo boxes that look very similar to modern metal machine gun boxes.
I don't want a real one:
But reproductions? That'd be fun. Or just the hardware to make my own. It wouldn't be too hard to make up a bunch and paint them olive drab.
They hold .30-06, but from the outside they are about the size of a .50 BMG metal box. The stout wooden size accounts for the size difference, I'm sure.
