Detail of the engine's "master" ID plate, between the gimbal outrigger arms in dsc66981.jpg. It reads

Rocket Engine

Contract No.: [unintelligible]
Part No.: 104001
Spec No.: [unintelligible] 142068 [probable]
Stock No.: [blank]
Serial No.: F-5036

This photo was taken in 2009. The ID plate has quickly degraded, as this photo from 2012 shows. I fear that soon the identifying marks will be gone from this engine.
