Baldwin Brothers and Company, 1876 NY list - http://books.google.com/books?id=6CcoAAAAYAAJ&pg=PA229&dq=Baldwin+Bros.+%26+Co.+N.Y+importer ,
of 72 Broadway, N.Y., was the importer of/for Whitworth gun tubes. Anyone have any examples or info noting Baldwin Brothers & Company on the Whitworth tubes?

In 1883, rough bored tubes were first addressed/considered. The of course in 1890 and also 1894 the term "barrels" was contained in the law/tariff. But in 1897, and more than likely the Dingy tariff bill, the wording is "shotgun barrels, in single tubes, forged, rough bored" - free - http://books.google.com/books?id=2pEaAAA...barrels&lr= , while double barrels were $3 plus 35%. Also note that combination barrels were a separate category. The term "forged" is where the U.S. goverment took Baldwin Brothers & Company to task asking if Whitworth tubes were "forged" or not.

Kind Regards,
