Piece of Space Shuttle External Tank Lower Strut Assembly, 4 x 5.5, with black numbering to the front top reading, “[A]SSY 10754–0001–105, 2000340.” Also written on the lower metal half in red ink is “Class 3 Not For Flight.” Metal reverse has additional black numbering, “ASSY 10754-0 [indecipherable] 103, S/N 2000340, Made from, P/N 10176-00 [indecipherable] –001, S/N 2000116.” Attached by a clear plastic tie is an orange “Non-confirming material” tag which reads, “LRV–FES–VAB, PV6–311032–Z.” Accompanied by a copy of a 1996 NASA “Problem Report” document specifically mentioning this piece by part number “LRV–FES–VAB, PV6–311032–Z” and “S/N 2000340,” and consequently instructing, “Part to be used for training or engineer evaluation.” This piece comprised part of the linkage that connected the Space Shuttle's large External Tank (which stored liquid propellant for the Space Shuttle main engine) with one of the two Solid Rocket Boosters (SRBs). During flight, the linkage was severed and the SRBs jettisoned after they expended their solid propellant. RR Auction COA.
