This tool post was seen in a 1910 catalog from O. K. Tool Holder Co.: "The O.K. Tool Post holds the tool on the side, thus enabling one to get up near to the chuck or face plate. With this tool post the tool is adjusted vertically, thus keeping the clearance on cutting tool always the same. The tool post swings around at any angle..." The No. 1 model, suitable for 14" to 18" lathes, was priced at $10. The No. 3 model, for 30" to 40" lathes, was priced at $30.
