Gorgeous Rickman Spitfire, there can't be many about.
A65 spitfires came as mk2, mk3 and mk4s, so I suppose the A10 version was classed as the mk1, but even so, changed quite a lot from the 57 original with Gold Star running gear, to using A10 running gear from 58 through 60 then back to the Gold star 61 to 63 where it was known as the Rocket Gold Star Spitfire Scrambler. Interestingly only the 57 had low run pipes and dual seat.
