Photograph of a Lear Research and Development Division machinist at work, September 1950. A balding man in glasses and a lab coat stands left of a large "Bridgeport" machine, which uses a needle-like device to poke through a metal piece, on a long base. The device has a large black wheel, at right, and an assortment of knobs and switches. In the background, what appears to be a door can be seen.; Photoprint reads: "Experienced machinist taking a light weight torque testing fixture for experimental servo-mechanism. Many development projects call for specially built test equipment produced in Lear's model shop. A sound-proof room is avialable for testing of mechanical devices and to house noisy equipment during life tests".
