This is a 1:18 scale PA-120 40mm ammunition can. This version does not open and is hollowed out from the bottom to cut down on cost, making them better for bulk display. You get 8 ammo cans in one set with this model.
See my other products in my Shapeways shop
for an opening version of this model as well as 1:18 scale models of other ammunition cans and diorama pieces.
