Antique International Time Recording Co. Secondary Slave Clock Ibm 1925 For Sale
Antique International Time Recording Co. Clock IBM 1925
This is an old time clock made by the International Time
Recording Company that later became IBM. It is dated inside on a piece of
paper September 22 1925.
Also on the label is “Shipped to Pennsylvania Edison Co. Easton PA” Style #
312A, Order # E35049, serial # 298807.
The piece measures approx 15” x 15” x 4”. I do not know if it works. The
solenoid unit inside is marked 48 volts. I believe this unit was a slave to a
master unit that would send a pulse signal every minute, activating the
solenoid coils. It is not a motor driven clock. The condition is fair to good
considering it was used in an industrial setting almost 90 years ago. There are
spot stains on the wood and someone wrote
9-22-25 on the front
cover in pen. It would be an easy project to refinish the cabinet but I like to
keep old things original if possible. The patina of the wood gives it
character. This would make a nice
display piece or a fine addition to an IBM collection.
