Hammond No. 12

Serial numbers begin around 68,000 but some prototypes are late 50,000. The 12 got several upgrades that made it worth the switch from older No. 1 and A&S models. Not only did it incorporate the No. 2’s anvil and shuttle system, but the 12 also added:

  • A margin adjustment key;
  • Blackened crown;
  • Blackened eraser board;
  • Two posts for the impression strip instead of one;
  • Mesh paper tube;
  • One piece paper rest which debuted with the 12 and thus a big giveaway;
  • Mounted backspace key;
  • Ribbon vibrator to type in two colors; and later
  • The anvil lock was simplified.
