came in ivory or brown. Dispatcher had the luminous numbers.
BELOW: 1938 version of the Attendant had a striker that sounded against a flat piece of bakelite. I believe this clock, the 7F77 and the 8F51 were only Telechrons to try this alarm method.
(ca. 1940 version left, 1938 version right)
The case (this model is quite uncommon in that there is only a single case piece) rear was opened up to make the alarm louder. It wasn't really necessary and subsequent versions had those holes sealed. The case on the left is rare in that it actually carries its own design patent just to the right of the model number. Most models weren't in production long enough, or Telechron didn't take the time to include it (the laundry list of mechanical patents is a different story). Other differences in the 1938 version were a flat bezel, different numerals and black hands (on the Attendant) instead of brown.
