Slide Rule
Bought this slide rule when I was attending University towards an Engineering degree in the late 1960's. By the time I graduated in 1971, these instruments were virtually obsolete having been replaced mainly by electronic calculators. I've never used this or any other slide rule in my subsequent working career.
