Rare Thrust-To-Weight Indicator Used to Measure and Display Acceleration During Lunar Landing. From the Lunar Excursion Module Simulator (LEMS) used at the Manned Spacecraft Center in Houston Texas, this T/W Indicator (thrust-to-weight) was a device which consisted of a moving pointer on a fixed vertical scale illuminated by an electroluminescent lamp. The scale was calibrated from 0 to6 lunar g and hermetically sealed in a magnesium enclosure. The inside mechanism was a simple accelerometer consisting of a seismic mass, guide rods, a cord, a pulley, a calibration spring, a damper assembly and a pointer assembly. 4½ x 2 x 1½". Great condition and comes with photo as it appeared in test console, and technical specs. Estimate Value $300 - 500
