Cutter and Shaper Head
|
Otto A. Miller |
Detroit, MI |
During the early 1920s, the inventor's company, Otto A. Miller & Sons, manufactured the grinding-wheel dressing tool of patent 1,387,427, but we can find no mentions of this firm from 1928 or later and so it is unlikely that they ever manufactured this cutterhead. |
