The lid opens and hinges to the rear, it's the first pattern; they were later changed to hinge from the side, where the lid lifts off to the side, not the rear. These first pattern boxes also do not generally have a handle on the lid, from my experience, only the side handles are present. I've got two, they are clumsier than the later ones with the handle on the lid, probably why they changed; they are 500 round cans, two belts.
