mitsubishi spring driven wall clock-information please

Hi. Just purchased a spring driven wooden wall clock with chime. Looks like a copy of a 19th c. American clock. Round face has hinged 8.5 inch bezel glass door and a hinged six-sided rectangular door over the pendulum compartment. Glass on the pendulum door appears old, warped with imperfections and has the word in English "clock" in gold letters. Above the word "clock" is the “Three Diamond" logo for Mitsubishi. The back wall behind the pendulum there are two words Japanese works in English script, “mitsubishikaketokei”and “seizosho”. Any information about this clock would be appreciated. Thanks. Timely Fool
