**SOLD**

One of two injectors installed on the J-2 rocket engine, this unlike-triple design fed liquid oxygen and liquid hydrogen to the gas generator. Mounted on the J-2 fuel turbopump, the gas generator exhaust output drove the fuel and oxidizer turbopumps to feed propellant at the required pressure to the rocket engine's main combustion chamber.

First image is the injector output (two spark igniters resulted in combustion on engine start). Second and third images are the inlet ports for the LOX and LH2.

Quite rare; $475 shipped within U.S.
