Vintage Shure Reactance Capacity Frequency Dissipation Slide Rule

This slide rule is firm cardboard but appears to be homemade. Staples instead of rivets. Some staining and discoloration. Name and date written on it. And some tearing at bottom. See pics!

I am listing over 100 vintage slides and calculators over the next few weeks. Amazing slides mostly from 60’s and 70’s. I will happily combine shipping if you buy more than 1. I charge highest shipping + $2 each additional item. Shipping overage is refunded at time of shipping.
