Moore & Barnes Mfg. Co.

New York, NY (The Railroad, Telegraph, Electric and Steamship Builders' Buyers' Guide, 1897)

The 1887/1888 edition of The Mechanical News has a nice article on Moore & Barnes indicating they are producing the Colton's Patent Vises.  Refers to George A. Colton.  (See Picture Below)

In 1895, this company (perhaps as Barnes Manufacturing Co.) was succeeded by the Phoenix Hardware Company.
