Ron - it is interesting that they show the 9mm Browning Long packed in 50-round boxes. Have never seen one or heard of one in my life. If anyone has one, I hope they will post a scan on this Forum. I would love to have a picture of it for file.
The timing of the 1917 catalog is right. I don’t want to rewrite the U.S. part of my article on this caliber here - many of the Forum members should have it (Issues 443 and 444, 2005), but I will try to summarize for those that don’t. Although named the Model 1907, Husqvarna of Sweden did not start making their rendition of the Model 1903 FN-Browning 9mm Brng Lg pistol until 1917.
The case of the U.S.C.Co. box is odd. The color of the box - an orangish-yellow, should date it from before about December 1915, but the wording on the box makes that almost an impossibility. The box says “Designed for Husqvarna and other Automatic Pictols” on the lid. It is hard to accept that U.S.C.Co. would have entered into a small production for commercial sales in Sweden for this ammunition in 1917, with America just entering WWI, even though Sweden was a Neutral Country. However, it is not impossible. These rounds have the “US” intertwined primer, as well, which was discontinued, I believe, about 1926 when Winchester acquired the Company. I would place the actual dates of probable manufacture at from about 1918/1919 until about 1925. It is also widely accepted that this was not a Swedish Government contract at all, but rather for commercial sales in Sweden. Sweden made this caliber as early as 1910, for the FN-Brownings they purchased before making the gun themselves. A search of catalogs and price lists from USCCo dated from 1913 until February 5, 1936, found no listing for this caliber at all.
Remington is a different story. The UMC production log, continued for a short time after the merger with Remington, lists the entry “9m/m Browning Long M.C., Jan. 1914 Commenced making for export.” There is no further entry. Now, did they really actually continue serial production, with the War in Europe beginning? Hard to say. The round is not listed in the January 1914 Remington-UMC catalog, but it is, at the least, found in Remington catalogs from January 1917 until February 1917, again timed very well for the production of commercial pistols of this caliber in Sweden. The 1922 Remington Catalog includes the 9m/m Browning Long among the newly introduced “Oil-Proof” cartridges for automatic pistols.
Guy - a comment you made about two different bullet jackets interests me. My notes and my collection, three different rounds (U copper primer, U nickel primer, plain nickel primer) all have tinned bullet jackets. I have never seen a Remington round that didn’t. Doesn’t mean they don’t exist. Can you expand on that comment?
