Seth Thomas Wall "Arcade" case only, ca. 1909. Oak case is 23.5 inches across the front; original painted dial is 18 inches. Key lock bezel below 6, bezel hinges from top. For some reason someone drilled 4 small holes in center of what is a mint dial. This is a project clock; you have to find a 30 day movement, hands, etc. Complete large gallery clocks of this size are bringing $1,200-$1,600. Ly- Seth Thomas No. 580.
