  • Annotazioni
  • Vibroplex Vertical or Upright or Wire Chief's Key.
    Responding to the need for a key that took up very little of the space on top of the table of a busy wire chief, Vibroplex designed a vertically-oriented version of their Model "X".
    Since they are very hard to find, Vibroplex must not have been able to sell very many of them.
