An advertisement placed by Greenfield Tap and Die Corporation (GTD) in Greenfield, Massachusetts, ran in Aero Digest magazine during World War II. GTD was the world’s largest maker of taps, dies and gauges. They produced measuring devices that insured an accurate fit for all parts produced anywhere in the country and allowed for mass production and standardization. One result was that the Air Force was able to use salvageable parts from old damaged planes called “Hangar Queens” to fix other planes. These kinds of efforts on the homefront helped to win the war.
