A few more comments regarding Browning…
The Browning brothers did make single shot rifles themselves in their shop in the mid/late 1800s. All subsequent designs for the next few decades were purchased by Winchester and produced or shelved. Upon designing the first autoloading shotgun, Browning and Winchester had a falling out, after which FN began producing that design. About that same time, Browning began partnering with, or selling designs to, other firms like Colt and later Remington. As far as guns bearing the Browning name, there were the original single shots made in the brothers’ shop (less than 600 made, and most of those remaining appear to have been well used), those produced by FN, those produced by Miroku, some produced in the US like the Buckmark, and probably others I don’t remember off the top of my head.
