Good used slide rule. Has wear, discoloration, and light scratches as expected from age and use. Please see photos for size and condition. Please see my store for other slide rules and circular slide rulers.
If you buy other items from my store the same day, I’m happy to combine shipping (through a refund of excess shipping costs).
