Rocketdyne large unused RP-1 rocket fuel bellows flexline of the type used in early production F-1 engines (through Apollo 4). Component is constructed from high alloy stainless steel with an inner diameter of 9″ and outer diameter of approximately 11″, and has a highly-polished cover made to keep the bellows from over-expanding and for structural and thermal isolation. From an early stage in production, the only markings are “R” ink stamps with small letters “NAR” for North American Rocketdyne, as well as two “NAR” lead inspection seals where the polished shell is wired together; no etched part numbers or inspection stamps are present. Originally found with a matching example in a box labeled “Bellows Assy., NA5-26772-3B, DK 226-1290.” In fine condition. A visually appealing display piece with its mirror finish.
