Henry W. Groves |
Indianapolis, IN |
D. C. Prescott's 1910 monograph, "The Evolution of Modern Band Saw Mills for Sawing Logs", says, "...Next, we have the celebrated Gold Dust Mill built by Sinker-Davis Co. of Indianapolis, Ind. They were advertising this mill in the Southern Lumberman as early as 1884 and were building band mills for some time previous. Their improved mill of 1885 is here shown, wood rims with rubber faces composed the wheels, and their market was the middle section of the country but never in the mills of the northwest." |
