    Apollo RCS engine with nozzle

    Apollo Lunar Module Reaction Control System Marquardt R-4D Rocket Engine with Extended Nozzle, Manufactured in 1965. A rare offering of an original rocket engine as was made for NASA; sixteen of just such an engine as this were mounted on the exterior of each Lunar Module in four quadruple clusters and sixteen as well on each Service Module. This piece of history has three separate ID plates, one each for the "Valve Assy-Solenoid, Fuel" and "Valve Assy-Solenoid, Oxidizer" assemblies, and one for the entire assembled part which bears the following information:

    "ENGINE-ROCKET Part No. X229663 Ser. No. 0002"
    "Contract No. P. O. FH-485520 Insp. Serial No. 055860000164 Date 3Q65"
    "Marquardt Corporation Van Nuys, California"

    There are several other numbers scratch-engraved and printed on the part as well, including one with a Serial Number of "001". 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. Overall, 13" long. First we've offered with the original nozzle extension. Incredibly rare and desirable, worthy of the finest collections. A tiny piece of the Oxidizer ID plate is missing. Excellent.

    This was my first time dealing with an auction house, and I am 100% completely impressed with Heritage. There is not an aspect of this process that I have a critique for.
