Wow. Stout observation that I have 4 boxes. I figured the description on the end would be enough for some of the more experienced people to know what they are.
jaguarxk120 was correct, it is unusual for the fiber box to stay with the part; normally the box does not survive, and then it would be a guessing game when determining if the contents match the label.
The bushings in the boxes are part of a shotgun reloading press that was made in the late 50s or early 60. I could say 'if you are lucky' but there is a chance you have at least one set of bushings.
There is a chance your bushings will fit other presses.
The bushing will also fit the 155, 266, and probably other Pacific shotshell loaders. Looks like some are marked for shot and the other one is marked for powder. Back in the day, I machined several of these.
