Seth Thomas Metronome De Maelzel, wooden pyramid body with mechanical wind-up movement. Pendulum swings and keeps time. Tick is audible and consistent. Gently used with minor wear to the wood finish. No cracks or breaks to the case. All tempo markings on the front plate are legible. Weighted pendulum bob is intact. #seththomas #metronome #demaelzel #vintagemetronome #mechanicalmetronome #musicaccessories #windupmetronome
