The Tariff Review October 15, 1897 http://books.google.com/books?id=xngpAAAAYAAJ&pg=PA202&dq We suppose that the gentleman making the statement that no gun barrels are made in this country referred to barrels made of iron and steel, such as twist, laminated and Damascus. If so, he was correct, for no barrels of that nature are made at the present time in this country. Gun barrels, however, are made very extensively here, but they are made from plain Bessemer metal, the same as is used in rifle barrels, and are used in the manufacture of single guns and the cheaper grade of double guns.
