I just bought one.
I like how the box is formed similar to many medal cartons (Shuco and FLL), the cardboard is warped due to moisture and the rust on the staples is dark not red. When I tuned it around quite a bit of debris/dust came out. You can also see how the sun light exposure has discoloured it. Also one of the spring on the clips was very tough/seized.
I was wondering if anyone else has come across them before?
I found a similar one without the ink script in one of T. Johnsons books and a cardboard one in Heersdolch textbook. Neither have the same script.
Looking to hear what others have to say.
Here are some additional photos:
