This product is a vintage Faber Castell 57/89 10 inch slide rule, made in Germany. The slide rule is made of plastic and comes with an instruction manual.
The case is missing its end, there is just the main sleeve.
The manual has a brown stain that goes through most pages but all pages can still be read.
Condition of all parts are shown in pictures as best as I can show them.
Any questions, please do ask.
