Rolls Royce Merlins.

I had read somewhere that the RAF does not own, or never has owned a RR Merlin engine.
These have always been the ownership of Rolls Royce by all accounts.

I think there is a shelf life of so many years or if an expired running time is reached then they are sent back to RR for servicing etc.

A couple of questions.

Was it only Merlin’s that it applied to or did it include the Griffon’s too?

Does this apply to private owners or can they have them serviced by anyone?

Just curious.

Brian.
