Manufacturers of Instruments That Stay Accurate.

Helping America Measure Up.

We can feel sure that the men who fight or battles are fully equal to the mighty task that faces them., But the planes, tanks, ships, and guns they fight with must measure up, too. Electrical instruments are a small but extremely vital part of America's war machine. 

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.
