UK P51Ds – Can you identify this one?

I am trying to identify a P51D which did a low pass over the polo field in Taunton where we were flying R/c aircraft, pm on Friday 13th Jan (no, not a joke). Nice pass going North to South No complaint, but it definitely positioned particularly for us (or the field) and did a wing wag before climbing away.

Bristol ATC knows nothing. Exeter ATC knows nothing. Yeovilton ATC weren’t active that day. But it was definitely a P51. It apparently did the same thing on the following Monday. Someone else saw it from a different location and definitely thought it was a P51.

It came straight over the top of me. Plain metal underneath.

All rather curious. So which one was it I wonder? As a first step does anyone know how many P51Ds there are on the UK register and, where they are located? I know there is at least one at North Weald and there will obviously be at least another one a Duxford.

Any help will be gratefully appreciated.
