I have listed a slide rule by the Faber Castell Co. This ruler looks to be in real good condition. This has the number 2/82 N, made in Germany. I do not know if this is a part number or not. It also says CASTELL DUPLEX. The booklet with it is written in German. I could not read it if I tried. If you have , please ask. Thanks for looking. This is the second of three slide rulers listed. Please take a glance at the other two. Thanks again.
