We now seelots of them on the secondary market probably because the original ownershave moved on to be with the head timekeeper. Without getting too technical, I will just say it runs on atmospheric pressure, and it is running and keeping time. The serial number of this clock is No. 171522. On the bottom front is aplaque which can be removed if you desire. It was attached with some pretty strong glue. The top lifts off to access the movement.
