Slide 10: AT&Co With Stop Works

  • Another example of a good collectible is finding an AT&Co movement with a stop works barrel, even if the works are missing.
  • Of course finding the complete works would be like finding a pearl when opening an oyster.
  • This feature is not easily determined (see paper), and it helps to know the serial number range where it existed; approximately 20,000 (Oct., 1859) to 490,000 (Dec., 1870).
