TRW's Lunar Module Descent Engine (LMDE)/Descent Propulsion System (DPS) no. 1021 (if the number taped to the support rig is correct/accurate), is manipulated by TRW technicians. Note what appears to be a wall-mounted LMDE poster/print in the background on the right.
Per a Boeing report, dated 28 October 1968:
ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19700027045...
LMDE no. 1021, along with engine numbers 1015, 1020, 1023, 1024, 1025, 1025, 1028, 1030, 1034, 1036, 1037, 1038, 1039 and 1042, were the subjects of an analysis on the performance of "production configuration Apollo Spacecraft engines".
While I doubt it ever flew, 1021 does appear to have the distinction as having undergone the earliest acceptance testing, 14 July 1966 (at least WRT specific impulse measurements), out of the above historic, trailblazing & distinguished group.
Too too much useless peripheral information? You betcha...but I'm retired, so I have the time - at least for now - to go down rabbit holes for this kind of obscure sh!t...and I enjoy it - at least for now. ;-)
