Here's a 2624GRC master with accompanying bellboard. The GRC master clocks ran synchronous slaves (with second hands). They corrected once an hour, usually during the 58th minute. |
 |
This is an AR-3 slave clock. |
 |
This is an AR master clock, model no. 14. Notice the program tape on the left. The early pendulum-based AR master clocks are quite a find! |
 |
This is a double dial GRC slave clock. |
 |
This is a 5-inch silver "pilot clock". The pilot clocks were usually found on the inside of the wooden master clocks. There was a pilot clock for each clock circuit. The pilot indicated what time the rest of the slaves said, so that you could advance that circuit to the correct time. |
 |
Here's a 24V version of the pilot clock, with a white dial. |
 |
And here's an 8-inch pilot clock - notice the "The Standard Electric Time Co." logo on it. |
 |
Here's a picture of a original Standard Electric issued program tape. The ones I obtained from Standard Electric a couple of years ago are green, but function the same way. :) |
