Seth Thomas oak mantle, the third and last of the "Fleet Series", ca 1909 to 1915. The only difference in this one from the others is that it has an alarm, sounding on a brass bell, and the dial is a tad better. 8 day, striking half hours, running. Not a dimes worth of difference in the 3 clocks. He had acquired the set in about as good of condition as you could hope to find. Ly-Seth Thomas #1108.
