Bumping this guy up with a tiny bit of new info. I think word has been spread around that the MTM Case-Guard S25 12g shotshell box is indeed actually correct. The thing is they changed the design at some point. Modern S25 12g boxes have a different shape than they did in the 80s and have a hinge on the lid instead of just plastic that could wear out. I'm not sure when the design changed exactly, but I did manage to find myself some "vintage" S25 boxes!
They look identical to the modern 20g boxes, but are of course slightly larger. They came in green and red. As you can see the brand and markings are all identical. Just need to find the 'old style' to get the screen accurate box.
