Thomas Baker was born on the 25th of September, 1800. He owned a gunsmithing business at 88 Fleet Street in London, and patented a type of hammer for percussion revolver in 1852, which had a notched cocking handle attached. This hammer achieved fair popularity with British revolvers of the time. In 1857, Frederick T. Baker took over Thomas' business and produced hunting shotguns until the twentieth century. Thomas Baker passed away in his late 70's in 1879.
