The box Lew asks about is white with a red label. I have the same box & it is unfortunately also empty.
The white 2-piece half cover box I pictured has a dark green under-label which states it was originally for the C .380.
It is the same size and color of the red labeled box in question. So it would/could have held the 9mm Luger as the red labeled box and has now been over-labeled for the 9mm Glisenti and Beretta.
Lew asked for other boxes that might help identify the red labeled box, thought to be a pre-WW II US market box.
So if the white box it’s self, is the same, & by size & form it is. So this white box I show could perhaps have sat empty & unlabeled until it was needed for the red label?
Which if as you note it was WW I / post WW I era, it would then date it to pre-WW II & very likely make it a product of GFL (the dark green under-label shows the GFL logo).
Thanks for the comment about my box being nice.
