An old Bullseye box:
i've got one too. did you get the spotting scope?
I've still got mine.
No scope. Is that what this is for?
Unfortunately, all the guns had been sold, but for $525, I got his safe. I don’t know what brand it is, but it’s a beast, I’d guess 800 lbs and 60x42x30, looks like at least 8 gauge steel. It’ll probably cost almost as much to get it moved.
That clamp is to hold the lid of the box in the open position. You'd open the lid all the way so it sits on top of the box, then slide that clamp over the hinged part. There was often a spotting scope mount on the inside of the lid that you could adjust so it'd fold into the box when closed and then bring up to place the scope where you could lean over and check your target without disturbing your foot placement.
