I have the three boxes pictured below in my collection. I am trying to date them. They are identical with the BKIW end labels. The only difference is that one is stamped “rostfreis Zundung” which I believe is “Rust Free Priming”. Another has the “NICORRO” overlabel in the top left which I believe is also a Rust Free/non corrosive marking.
Does anyone have a an idea when the “rostfreis Zundung” stamp and the “NICORRO” sticker may have been introduced. The date stamps on these three boxes are, top to bottom: “233 a V”, “395 a” and “266 s V”.
Any help dating these boxes would be a great help, even hints at a date are useful.
The BKIW was used from May 1922 until 1936 according to information I have, though there are some uncertainty on the 1936 date. It is unlikely that DWM produced 9x19mm ammo commercially before the late 1920s or early 1930s, but I don’t have a complete set of export catalogs to confirm this. Two of the boxes (both non-corrosive marked) have “Stoeger” labels on the side.
