WW2 Era Lockheed Martin Aircraft Manufacturers Workers Perpex Badge

This is a real 'homemade' badge, dating from the WW2 era, it was made by a worker at the Lockheed Martin company out of a Perspex disc with a transfer of the company logo to the front and a small safety pin attached to the back with a glued piece of plaster. I googled WW2 Lockheed Martin and found a great lengthy article about the company and their work with the RAF during the war, its worth finding and reading. The badge comes in good but aged condition and measures 1.75 inches long.
