A Rocketdyne J-2 Engine Ignition Exciter, measuring approximately 11? long and 3? in diameter, marked in black text on one side, “General Laboratory Associates, Inc., Norwich, N.Y., Ignition Exciter, P/N 4260 Date Mfd 12/65, Change B, S/N 60, Rocketdyne Spec. NA5-27383-2,” and triangular NASA stamp. Retains its original parts tag, noting that it was removed from Rocketdyne J-2 engine J-2037 in January 1973, due to “leakage.” This part stored a high voltage electrical charge and functioned much like an ignition coil, giving the J-2 engine its crucial ability to restart while already in Earth orbit; this was used on the Saturn V 3rd stage (S-IVB) for the critical trans-lunar injection burn. In very good condition, with scattered marks and dings to the metal housing.
