Actually, the m/07 designation for the Husqvarna pistol doesn’t appear on the box label, but that was the designation for this pistol throughout its production and use, including the FN-made pistols supplied to Sweden prior to Husqvarna’s production. I am not sure how the appearance of the Husqvarna name on the label can establish any time period short of the entire production and use of the pistol, although I agree that other factors concerning the label do limit the time period.
As far as I can tell, production of the 9 mm Browning Long cartridge, designated 9 mm Skarpa Patroner m/07 in Sweden, began a number of years before 1916. The first Swedish factory to make this cartridge was Ammunitionsfabriken Marieberg, using “M” as their factory designator. Production there started in 1910 (I have a 1910-dated cartridge from them, as evidence of that production) and went on thru 1942, with some gaps in the known production. For more information on that, see “The 9 m/n Browning Long Cartridge - Part 2,” Woodin Laboratory, compiled by John L. Moss, page 44, IAA Journal Issue 444, July/August 2005. The first part of the article is in Journal 443.
The January 1914 date for initial production by Remington-UMC is confirmed in the UMC daily log, which continued, sporadically it would see, after the merger in 1911 with Remington. The entry has one very interesting note that relates to previous entries on the thread on the Remington boxes concerning the destination(s) for the Remington ammunition, “9m/m Browning Long M.C., Jan. 1914 Commenced MAKING FOR EXPORT.” (emphasis on the last part by me).
There was more on the Remington production, but it is not germane to this particular thread.
I should have read my own work on this cartridge, concerning the date of the U.S.C.Co. box label. It should be before about December of 1915, when orange packages gave way to a blue and orange style. However, this seems impossible due to the use of the Husqvarna name on the label, relative to the intended weapon-use of these cartridges. Husqvarna did not begin production of the m/07 pistol until 1917, so it would seem to be unlikely that this box could even possibly be before that date.
This caliber of ammunition is not listed in any U.S.C.Co. catalog that we had access to during the writing of the article in question. The story continues, but is too long to relate here. It is suggested that the two part article in the IAA Journals of May/June and July/August be consulted if there is further interest in this subject. As I mentioned, I should have done that myself. I will just conclude with the belief that, for various reasons, the box shown should date between 1917 and 1926. There are even questions regarding whether or not this was ever a contract for the Swedish Government. The first 300 Husqvarna pistols are known to have been for the commercial market.
