Flight Ready Hardware Lot of six pieces of stainless steel hardware including (3x2 diff.) pieces that may have been part of a cooling system. Each of the pieces has four hollow tubes rising perpendicularly from a tubular base. One set of the tubes measures 2.5", the other 1" long. Each piece is double bagged and sealed with yellow tape. There is a red NASA "Cleaned for Service, July 28, 1976" tag on each package. Scarce and interesting.
