Taylor instruments used the brand tycos on its instruments from 1907 to 1932. This example is in working condition. The glass appears to be a replacement that isn’t quite the right size, so the bezel doesn’t fit tightly. Brass case is 5 3/16″ across the top bezel, and 6 7/16″ across the back flange. See photos for condition details.
