    Cool Rule!
    Here's a nifty vintage US slide rule.  It's a pretty basic 10" slide rule from Engineering Instruments Inc. of Peru Indiana.  It's a light wooden rule, model 250.v, with a plastic laminated surface.  Reverse side has copious conversions / formulas printed on it. Comes in plastic sleeve case. Clean & good working order!
