1-32Qualitron Q-1437 "Slide Rule" Calculator USD29.95

The Qualitron 1437 is an early "slide rule" calculator from a once well-known manufacturer. It only had limited "slide rule" functionality: no logarithms or trigonometrics on this calculator!

This particular machine, though obviously used, is nevertheless in good working condition. The display is clear, keys are snappy, and there's only some minor corrosion on its battery terminals.
