VTG 1930's International Time Recording Industrial Metal Wall Clock

Vintage International Time Recording Wall Clock. Tag on back of clock has a lot of information! Patent date of July 22, 1919. This specific piece was sold to Charles Carey in Penn Yan NY on Jul 27, 1930. The tag has the old IBM logo and states that the piece was Manufactured by the International Time Recording Co Division of International Business Machines Corp! This model used Style No. 14-47 and is a 24 V DC clock. The clock measures 15 3/8 inches across. The glass and the clock face look great! The glass is loose and can be moved by pushing with your fingers about 1/8 inch within the metal rim. This very well may be how the clock was delivered originally.  It could be this is how it's manufactured. Also there are quite a few scuffs to the paint on the metal rim. The wiring in the back is as pictured. I have not tested the clock. I assume whomever buys it will have the expertise I don't! :) This is a great antique clock that would make a nice addition to anyone's collection!
