    Description

    Apollo Lunar Module Rocket Engine, Reaction Control System Marquardt R-4D. A rare offering of an original rocket made for NASA; sixteen engines just like this (with an extended nozzle) were mounted on the exterior of each lunar module in four quadruple clusters. This historical relic has three separate ID plates, one each for the fuel (plate slightly damaged but numbers present and readable) and oxidizer valve assemblies, and one for the entire assembled part which reads, in part: "ROCKET ENGINE, REACTION CONTROL/ Part No. X-20796/ Ser. No. 1013/ Date 3Q64 ". There are several numbers scratch-engraved on the part as well. The Marquardt Corporation was awarded the contract to build the reaction-control rocket engines for the Apollo spacecraft in 1963. They were first flown in the unmanned Apollo-Saturn 201 test flight launched in February 1966. Designed for maneuvering in space, this was a bipropellant engine using hypergolic nitrogen tetroxide and hydrazine as propellants, generating 100+ pounds of thrust. This was obtained from the estate of a Grumman engineer. Excellent condition.

    The pre and post sales experience was wonderful and flawless. Heritage has the best in-house operation I have ever seen and their people are not only professional but fun to work with, especially Steve C.

    As for Heritage's online system… Yes the interface is more complex than what we are used to with SAN but what is behind that interface is amazing for sellers and buyers alike. It is real time and for a real serious auction buyer there is nothing better in the auction industry, bar none.
