I had an encounter with some kind of aircraft at my school yesterday. There I was, in the smaller field of our school with two of my friends, and we hear a sound. Something odd....
We looked about and out of nowhere comes this aircraft, heading straight towards us and descending fast. Then it made a bank, showed off it's underside and zoomed away.
None of us knew what it was, and two of us (me being one) are rather good at identifying aircraft. This aircraft had the shape of a warbird, and when it banked away, I saw what looked like Royal Navy roundels from WWII, and the aircraft itself was coloured like so on the Douglas Dauntless on this image here (for those who don't know the Dauntless is the bottom one

We had a hard time identifying it thanks to the way it looked. At first, I thought it was a Seafire, because of it's Spitfire-ness and the RN roundels and colours, but as it banked I saw that the wings were clipped. (As far as I know, no Seafires had their wings clipped, but this is a guess - all the Seafires I've seen have had elliptical wings) I didn't get to see the tail well or the cockpit, so I was completely baffled as to what it was.
And later on in schooltime, I was in a classroom that sits right by the field, and I heard the noise again - it was back, and this time it made a low pass over the field, fortunately I could see the fuselage and tail perfectly now. The fuselage made me think even more "Spitfire? Seafire?" but the tail resembled that of a Mustang. This threw me off even more, and then I thought back to how the aircraft sounded. My other friend, who had seen a Mustang at an airshow, said "they whistle slightly as they come down", and this aircraft, when coming for me and my two friends, sort-of whisteld, more whined (but the noise of the engine was greater than this "whining".)
I didn't get to see if it had an airintake underneath to see if it was a Mustang, and if it were a P-51, it would have been an P-51A or P-51B. I said I didn't get to see the cockpit well, but the shape I saw was most definately not the "tear-drop" cockpit on the P-51D. But if it was a Mustang, why was it in RN colours?
Here's somekind of sketch I made of it, if any of you can help me identify this aircraft:

If any of you know of any kind of warbird-like things going on in the UK, were there any going on in Devon? (This is where I live and where it was seen)
Also, could this be somekind of "kit-plane" that somebody had built and wanted to show it off, or was it a warbird?
Thanks, hopefully we can identify it
