Old 1940s vintage electrical wiring guide book -Wiring Simplified - by H.P. Richter. It has 122 pages with tons of great illustrations and drawings. It covers different types and sizes of wire, wiring with conduit, working with old wiring, wiring around the farm, wiring electric motors and more. All based on the 1946 building codes, of course.
This has light wear and some minor dog-earing.
