The inside bottom of the box has two marks that I can see. the mark on the left is the "lion" and the mark on the right is the "R" with some symbols above that are shown in the image above.
The top inside lid of the box also has two marks, on the left is the minerva, but because of wear or whatever, I cannot discern any lettering of any sort inside the minerva. the other mark seems to be the same "R" symbol that is on the bottom of the box. \
I cannot see any other marks either inside or outside of the box.
Actually, now that I look at it again, there seem to be four lines on both the top and bottom edges of the box. Here is a photo... is that the Date Mark by any chance?
