Notes: "Faber Castell made a whole series of slide rules with Addiator-brand slide adders on the back, both wooden slide rules and later, plastic ones. This is one of the later 5 plastic ones, but unusual in that it is the Elektro model, 67/98 Rb, with scales for electrical engineering, rather than the more common Darmstadt or Reitz models. "
