This set consists of two wooden slide rules made by Engineering Instruments Inc of Peru, Indiana, and a light plastic pocket slide rule made by Sterling Plastics Co. of Mountainside, New Jersey. There are instructions for each. The slide doesn't move on one of the wooden slide rules (maybe needs some TLC). The plastic slide rule works and looks almost new.
Sizes: Full size slide rules are 10.5" long, and the pocket slide rule is 6.5" long.
