Prop identification and points of view??

Good evening all.
I wondered if anyone might be able to help me with identifying this prop on an arvor 215.
It appears to be marked with the following..
NG 40089RK
2007.02.28
any ideas? Is this the original prop or one that has been perhaps worked on?
She was out of the water this evening to be cleaned before a proper sea trial in the morning. Hoping that knocking off all the barnacles  from the prop and rudder will gain her an extra 8 knots or so....!
