Any RAF engineers out there?

Hi,

I have a question about this blade that a friend gave me.

He found it at an aero jumble, and was told that it was from an early Pegasus engine for a Harrier.

It’s 85mm long and I have written the numbers found on the blade on each photo.

I hope you can help me out with this one because I have no idea about this one,

cheers,

-John
