Pickett Microline 140

The Pickett Microline 140 is a simpler bright yellow (hard to miss on a desk) plastic slide rule, not as complex as the Keuffel & Esser slide rules in the collection, but more complex than the simple beginner slide rules. It’s a double sided slide rule with LLI/K/A/D/DI scales on one side and LL2(-0.1)/LL3(-1.0)/LL2(+0.1)/LL3(+1.0) scales on the other side. The slide has CF/CIF/L/CI/C scales on one side and B/Cos S/Sec T/ST/T/C scales on the other side.
