Identification for the engine closest to the door ("engine #1").

Picture 3 of 4.

Paperwork taped to the aft end of engine #1's dolly (recall that "engine #1" is what I arbitrarily decided to call this engine, so don't let the "engine #4" sign confuse you). Note the red thrust chamber cover (with the stylized white Rocketdyne "R") behind the railing on the dolly.

The paperwork reads

Engine #4

P/N	S/N	Nom.	Condition
9024460-11		Support Elect.	Good 1 ea.
4064/MOZ	J-1007	Eng. Handler	Good 1 ea.
103826	J-2103	J-2 Engine	Good 1 ea.
9020628-51		Support Fluid	Good 1 ea.
19-9020629	N109	J-2 Eng. Cover	Good 1 ea.

Yes, this indicates that the J-2 engine's serial number is J-2103, even though the engine is stamped with a "U/N" of 2148 (seeming to imply J-2148). To confuse things further, the dolly has a hand-made label indicating "J2 2146".
