Found this one doing storage duty for things other than .22 LR. As I remember, these came in paper wrapped bricks of ten boxes. Can’t remember if the wrapper had much info. I think the headstamp may have been something like the inter-locked ring logo seen on the box. No “Child Warning” or “Range Warning”. Only marking not shown here is a (6) digit lot code on the inside of a flap. These were bulk shooting fodder ca. early to mid 80’s (though I don’t know why I didn’t save a box as it is kinda neat…) What brand is this?
