Beautiful Apollo Command Module Reaction Control System (RCS) Positive Expulsion Propellant Tank. The tank was utilized to provide nitrogen tetroxide (N204) oxidizer to the Command Modules SE-8 attitude control thrusters. Within the tank is an internal bladder that was compressed by helium to expel the propellant at the required flow rate to feed the thrusters.
$2750 plus shipping.
