When the recovered F-1 engines were initially taken to the Kansas Cosmosphere's SpaceWorks division, some of the first steps in the conservation process were to document and disassemble the engines.

At the time I visited SpaceWorks in December 2013, I highly suspected that what was visible on F-1 engine F-107-1 at Science Museum Oklahoma, which I first visited in 2008 and which is displayed without its injector, was the aft face of the LOX dome; however, at the time, there were no photos on the Internet of the aft face of a LOX dome.

When I visited the F-1 disassembly lab at Marshall Space Flight Center in July 2012, it was my hope that I would be able to inspect and photograph the LOX dome's aft face, but it was sitting on a pallet with its forward face up, and my hosts told me that it was too heavy to attempt to rotate.

So, when I visisted SpaceWorks in December 2013, I was really hoping to be able to inspect and photograph a LOX dome aft face, but all of the LOX domes were in their baths with their forward sides up. When I mentioned how disappointed I was in this regard, my hosts offered to give me some photographs from the disassembly and documentation process.

These photos confirmed that what was visible in place of F-107-1's injector was the aft face of its LOX dome. The SpaceWorks photos also showed cylidrical sleeves with conical bases, used to protect the 16 inner-dome attach bolts which help attach the LOX dome to the injector.
