I purchased several Rocketdyne items from Norton Sales on July 23, 2013.
One particular part has a tag on it that states "Removed from 113D." The sales person from Norton Sales thought it might be from an Atlas missile, but wasn't sure.
Of course Atlas 113-D was the Atlas that launched Wally Schirra on his Mercury Sigma 7 mission in October 3, 1962.
I've done some Internet research to see if there is any mention of a valve being replaced on 113-D, but the only reference I could find that mentioned a part replacement was a valve on the Mercury capsule, and I doubt that would have been a Rocketdyne part.
I assume that this Rocketdyne valve was related to the engines or the missile/engine interface, but I haven't found any good photos or documents on the "boat tail" end of the Atlas. Because of the boat tail end is covered with a insulation blanket, good photos of the engine/missile interface are rare. It is possible that this valve was removed at Convair long before the missile was shipped from the factory.
Any help in locating information about this part would be greatly appreciated!
