Dominican Republic .30 Carbine Ammunition Box

The subject of the Dominican .30 Carbine ammunition has come up several times. Last week, I found this empty box packed in with other items. I fired up the ammunition many years ago, but the box remains. There are no other markings on the box - rear, sides, or ends, nor is there anything inside, like a lot number (it seems they didn’t use those). It is a two-piece box, with a sliding topless cardboard inner box, like the older .22 RF boxes.
