Pickett N-515-T

The Pickett N-515-T is a Cleveland Institute of Electronics branded slide rule and was part of the second batch of slide rules I acquired. It’s a single sided metal slide rule designed for electronics calculations. The fixed scales are (Lf) H/(fx) 2π/A/D xc/L/Ln. On the slider are Cr B/S/(Lx or Cx) CI/(XL or fr) C scales.

On the back side are a number of electronics related formulas.

Dimensions: 30.2 cm x 3.8 cm x 0.3 cm
