The Sterling Precision is a basic beginners slide rule made of plastic. It’s a single sided slide rule with A/D/K scales. The slide has B/CI/C scales on one side and S/L/T scales on the other side. There are three of these in my collection, two white and one with a greenish tint. Aside from the colour difference, all of them are identical.
Dimensions: 28 cm x 3.3 cm x 0.5 cm
