Case:
Polished Mahogany with glazed front
Size: 17 inches high, 19 inches wide and about 12 inches deep.
Movement:
Driven from a master clock as a slave, this has settings for days and hours and was used to time factory breaks and working hours.
Notes:
Commonly known as a "Bell Ringer" this item has a label which says "Pul-syn-etic Impulse Clock" and in other literature I have seen it referred to as an Adjustable Programme Instrument. It is a definite eyecatcher and I consider it to be very collectable.
The WORDING on the rear is "Ref 7F" and serial No. 1?046 (2nd No. in serial unreadable, possibly 0)
