Boss & Co. is an English gunmaker established in 1812 by Thomas Boss in London. Thomas Boss had previously worked for Joseph Manton, one of the greatest gunmakers of that period, before leaving and starting his own business. When Thomas Boss died, the company was acquired in 1891 by John Robertson, a gunmaker who used to work for Boss as an outworker in assembling and finishing guns.
Ernest Hemingway used a Boss & Co. shotgun in his 1961 suicide.
