Two ID plates, including the engine's "master" ID plate.

If you look closely between the gimbal actuator mounts you can see a silver sphere; that sphere appears in the upper left of this photo.

This is F-1 engine 114-2; Alan Lawrie's records indicate that this is a developmental unit which was in environmental storage at the Michoud Assembly Facility during a 1990 audit.
