Entrance portion to a Lunar Module Cleanliness tent. Manufactured by Grumman, portion is made of reinforced fabric with hemmed edges, and a two-zipper semi-circular entrance and numbered LDW420-11043-3. Portion measures 27 x 72. The complete tent would be set up outside the Lunar Module hatchway to keep dirt from getting into the LM cabin. Rolled and in fine condition, with some mild toning to fabric. Accompanied by a disc containing eight images of Grumman schematics and forms relating to the tent, one with an image of an engineering order from 1966 detailing the particulars of the opening, zippers, and specifications. Entry portion was originally purchased at the Charles Bell estate auction in 2000. RRAuction COA.
