Lew - I have two of the blue boxes in my collection. They are not identical to what you show, however, so not sure you want the info on them, but will give it on the chance you do. The only differences on them are that on the bottom of the label, actually rolling over the edge to the side label, is “OILPROOF” (which may be cropped out of the picture you show; I simply don’t know), and the words “U.S.A. Patent Pending” are printed right over the very bottom of the word “STAYNLESS” in blue print (the same color for the “OILPROOF” marking mentioned).
One box is for 9 m/m LUGER FULL PATCH and the other is for 9 m/m LUGER HOLLOW SOFT POINT. I would consider the the description of HSP erroneous, as the bullet, which is GM Truncated has the jacket rolling over into the HP. There is no lead apparent as in a SN bullet. Headstamp is W.R.A. 9 M-M, with a nickel primer and blue seal. There is no case cannelure, even though so-shown in the label drawing. Code inside the flap is 111 17. All three of the “1” markings are the same, indicating to me that all are the number one, in classic hooked “nose” and with the serif line across the bottom.
The FMJ box has a code of A91 22. This box has two box samples in it. Years ago, when I likely acquired this box, If I got a second box exactly the same, I would keep one round of each in only one of the boxes, as I considered the second box as redundant to my collection. I had no interest then in what I thought were “lot numbers.” Today, I would keep both boxes, but knowledge increases, and I have no idea what I did with the other box. Probably gave it away. The two rounds are a W.R.A. 9 M-M headstamp with identical characteristics to the HP round mentioned, other than being FMJ, and a round headstamped “W R A 9 M/M LUGER,” with a case cannelure, and nickel primer with red primer seal. The bullet is identical to that in the round of the first box.
To me, these should be WWII production, or shortly after WWII.
By the way, I just noticed that the “top label” is duplicated on both sides of the box, except that the second one, which I assumed to be the back label, does not have the “OILPROOF” or “Patent Pending” markings, and therefore are identical to the picture you show. Never noticed that before now.
Hope this is of some help.
