I bought this several years ago from Rick Boos. It was identified as a S-1/S-1B power supply, which I don't doubt. However, I know nothing about the history of this particular unit such as if it was a flight spare or was hardware which was replaced. If the latter is the case, then upon which Saturn was it intended to be flown? Can anyone decipher the meaning of the stampings on this item?
