Lunar receiving laboratory stainless steel containment vessel, approximately 6 x 6, designed to hold moon rocks upon their return to earth. This two-piece vessel has six bolts which attach the two parts together, as well as a carrying handle to top portion. Both pieces are etched with serial numbers X1-2-58, with the bottom stamped “Vollrath, Sheboygan, Wis.” A heavy-duty vessel such as this would have been used to store lunar samples under vacuum within the Lunar Receiving Laboratory. In fine condition. RR Auction COA.
