Selling a rare set of early1920s L. L. Cooke School of Electricity training manuals, which are hardcover bound by bolts. These manuals were published by the Chicago Engineering Works and are original prints from 1926. The manuals cover the topic of electrical education and are focused on electricity generation, control, and management. They were printed in English in the United States, making them a valuable collectible for those interested in electrical history and education. This set was used to train future Electricians and Engineers in electrical concepts in all industries.  These include Mining, Farms, Radio Electronics and other industries.  Manuals included worksheets that the student completed and sent to the school for credit.  Lot of different subjects.  Looks like it might be a complete set, but not sure.  This set could be used today for training.  Very comprehensive set that is very hard to find.  The work sheets and notebooks are in nice shape.  The illustrations are great.
