Possible spitfire propeller, can anyone help me?

Hello everyone, after reading through a few of your forums you all seem to know everything i need to know about my propeller that has been standing in the corner of my dining room for the las 15 years. It was given to me by an old man who was in the RAF in the ww2 and we gained it as a present as it was to heavy for him to move when we bought his house. I have had a close look at the bottom of the prop and it has three sets of numbers and from reading your forums i gather that they are Block number AC4861 or it could be a 7 Drawing number 234993L and serial number 13-0062/RA. Then there are the letters on the metal base which are D48647 , A120and J69-20/RA5813. The prop is made from wood but it has holes where metal pins have been down one side, it is 65inches from tip of prop to the start of the metal, it is 30 inches around the widest part at the base and it is too heavy to lift but in beautiful condition. I would be very grateful if you can give me some information on it and would love to find out what plane it used to be on, it is a real talking point when people visit and i would like to know more! I can send photos to anyone if they send me their email address but i dont know how to do it on this message, sorry as i would love you to see it, maybe someone could tell me how to do it?
