Engine identification plates, located between the gimbal actuator mounts on the No. 1 side of the engine. This shot has the left ("master") ID plate in clear focus.

Unfortunately, the "master" ID plate is damaged, and only a few digits of the serial number are visible. I actually photographed the ID plate at the right and the top of the "master" ID plate (at left) when I visited this engine at the old Michigan Space & Science Center. At the time of that visit, however, I did not know what a "master ID plate" was or really even know that the engines had serial numbers, and I did not photograph the serial number.

Nevertheless, these few legible digits were enough for Alan Lawrie to confirm the paper records identifying this as engine F-041, a development engine.

The "master" ID plate, at left, reads
