Remington “Blue Rocks”

[Bruce P Bruner]

I picked up 3 cases of “Blue Rocks”, I don’t know when Remington discontinued them but for $5 each it was okay. I haven’t even opened them so I don’t know what color they are. They used to have “Orange Dome” stamped on the cases but I can’t find anything on the boxes except the stamp in the photo. Any idea when they were made? The YD in the code may be for yellow dome and perhaps the 71 could be manufactured in 1971. The price tag’s say $2.99. I think it would be sort of nostalgic to dust them, or try to.
