K&E 68 1100 Slide Rule w/ Leather Case Keuffel & Esser Deci Lon 10 (or Deci-Lon 10) (the 10 denotes a ten inch scale)

Slide moves very easily.  No chips or cracks on the cursor bar.  Prior owners name on the inside of the leather sheath, and etched in the metal tab on the slide rule itself. The other metal tab has some marks of ink. These are minor marks that may come out
