It is sort of interesting to know that except for a few guns made in Utah and his inventor's models, John Browning never made a firearm. Browning was a free-lance inventor, who sold his designs to any company wanting to use them. Depending on the contracts, he could (and did) sell the same design to different companies. In the main, those companies even prepared the patent applications and obtained the patents in Browning's name.
To add to the confusion, FN early on found that there was magic in the Browning name and, under the original agreement, continued to use the name on guns that Browning had nothing to do with. Even one of the most famous guns to use JMB's name, the Browning High Power, was an incomplete "work in progress" when Browning died; the main part of the design is by Saive.
