Original 1943 electrical trade vintage ad for GENERAL RADIO COMPANY.  Main office and plant was located in Cambridge, MA

Quality Control in the General Radio Standardizing Laboratory.

However well designed an instrument may be, accurate calibration and reliability in service determine its ultimate usefulness. Testing, therefore, has long been an important final step of our manufacturing, approximately 10% of the total man-hours required to produce a General Radio instrument is spent in our standardizing laboratory. To carry out these tests, capable personnel, adequate test equipment, and reliable standards are necessary. Many of the staff have engineering degrees or are graduates of engineering institutions.

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.
