Robertson Mfg. Co. was founded by William Robertson ca 1900. They reorganized as the Robertson Drill & Tool Co. in 1909.
      The Frontier Iron Works, Buffalo, advises that the two-story building which it is now erecting, is to be occupied by the Robertson Drill & Tool Co., controlled by the Frontier company and by the Acme Pattern Works, a firm which makes all the Frontier's patterns. The drill and tool company will be moved from its present plant, 1848 Niagara street, when the building is finished, and will have sufficient machinery to equip the new plant. Later, the Frontier Company may be in the market for a few machines to use in boring cylinders.
      This company was direct competition for the W. Robertson Machine & Foundry Co.
, founded by William Robertson after he had left Frontier Iron Works.
