Serial number range

  • M-1001 to M-4745 (Grand Rapids, April 6 to December 31, 1931)
  • M-4746 to M-5609 (Grand Rapids, January 1 to March 31, 1932)
  • C-1001 and up (Oakland, April 15 to September 25, 1931)

Grand Rapids and Oakland shared one series of 6-75 car numbers, 1001 to 5609: each number was used only once, with M or C in front of it for the factory that built the car. So there is no C and M car with the same number.
