help identifying a spitfire propeller

hi there. i was wondering if anyone could help me identify what i think is a spitfire propeller.
i got this propeller about 15 years ago from a car boot sale and have never really thought about it since. i am now moving house and am considering selling it but i dont really know any details about it or what its worth. the serial number on it is RA10379/RTS. below that number is a red circle which also contains a set of numbers.
i would be really grateful if anyone could help me.
many thanks mark
