Original 1943 electrical trade vintage ad for G & W ELECTRIC SPECIALTY COMPANY.  Main office and plant was located at 7780 Dante Avenue, Chicago, IL.

Manufacturers of Subway Oil Disconnects.

Quickly isolate underground cable circuits with G&W Type "RA" Subway Oil Disconnects. Simple and safe sectionalization by merely operating external lever arms. No covers to remove. No seals to be broken. No links to unbolt. Oil filled tanks keep size to minimum, operating shafts perfectly sealed.

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.
