The sign accompanying the F-1 rocket engine. It reads

F-1 Rocket Engine

Five F-1 rocket engines powered the first stage of the huge Saturn V rocket, which launched Apollo spacecraft to the Moon. This F-1 was intended to be used as a flight spare for either Apollo 18 or 19, the last two planned lunar landing missions, which were canceled. The engine underwent eight start tests in 1966 for a total firing time of about 500 seconds.

The handler on which the engine is mounted was built to move F-1s within assembly buildings, repair shops, and hangars. Over long distances, another vehicle transported both the handler and engine. The handler originally transported the F-1 engine now exhibited in the Museum's building on the National Mall in Washington. It was later restored to hold the F-1 engine displayed here.

Note that A19700271000 is actually the inventory number of the F-1 at the National Mall facility.

The nozzle extension displayed with this F-1 (which bears the same serial number as an F-1 engine at the U.S. Space and Rocket Center) is D20050101001.

Also note that, for long-distance transportation, the F-1 was installed on a different type of dolly and the nozzle extension was shipped using a separate handling fixture (the photo in the collections database for D20050101001 shows both of these types of handlers).
