Original 1943 electrical trade vintage ad for the SOLA ELECTRIC COMPANY.  Main office and plant was located at 2525 Clybourn Avenue, Chicago, IL.

Manufacturers of Constant Voltage Transformers.

Constant Voltage guides the Tools of War.

From blast furnace to battle front.

Never before in the history  of warfare has precision production been so important as it is today. From the trigger group of an M-1 rifle to the fire control of the 16-inch battery, split hair tolerances are demanded in millions of intricate munitions parts.  Constant voltage is almost nonexistent on today's overcrowded power lines. Wartime consumers are busier. 

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.
