Rare Surveyor Lunar Lander Alpha Scattering Equipment bracket, 16.26" x 12" x 4", designed as a deployment mechanism for the experiment sensor head that would measure the concentration of various elements in the lunar soil. Upon a successful moon landing, the Surveyor Alpha Scattering Experiment sensor head would be released by the deployment mechanism and lowered to the lunar surface upon command via a nylon cord wrapped around a geared cylinder. In very good to fine condition, with overall scattered wear and marks from extensive use. A decidedly scarce and impressive piece of flight hardware.
