In 1874, this firm—variously named Key Stone Forge Co., Keystone Forge Co., or Keystone Portable Forge Co.—primary product line seems to have been forges and blowers for blacksmithing. There was a Keystone Forge in Reading, Pa. (which may be related to Gray Iron Foundry & Manufacturing Co., Inc.), and we remain uncertain whether the two businesses are one and the same.
