Slide rule by Pickett & Eckel that was made in 1948. The slide rule was used to do multiplication, division, trigonometric functions, and logarithms. The straight slide rules were not as accurate as the Atlas Slide Rule, which could get up to five figures, but were still quite good for school based work.
