The stator stages on a gas turbine hot section always look completely knackered on strip down. The RB199 was no exception. The M07 HPNGV module would be full of cracks and burning but it wasn't rotating and could handle the damage. I remember visiting Ruston Gas Turbines in Lincoln in the early 80's. The made industrial gas turbines that would run continuously for 12 years without shutting down, and on poor quality fuel too. The turbine blades eroded to something resembling thick needles when they were finally stripped down.
