Original 1943 electrical trade vintage ad for STACKPOLE CARBON COMPANY.  Main office and plant was located in St. Marys, PA.

Manufacturers of Molded Metal Contacts.

The First Silver-Graphite Contact ever molded from powders, was a Stackpole product.

Almost two decades have passed since Stackpole revolutionized circuit breaker and control equipment performance by producing a molded silver-graphite contact, at the suggestion of Westinghouse engineers, which enabled a 50 ampere continuous-rated unit to handle 5,000 amperes on a short circuit.

Unbound from a 1943 electrical engineering magazine, this unique old one-page advertisement would display beautifully matted and framed. Nice graphics. World War 2 propaganda. A fabulous addition to your retro electrical library.
