This unit is a 8-inch diameter metal tape reel; the front and back are both bare metal. On one side there is gummed residue spelling "UNIVAC," two illegible gummed labels, one foil label reading "PLASTIC", and a note reading "UNIVAC Computer tape." The ring in the center was a safeguard to keep tape from being erased.".
