Several surviving Mk XVI Spitfires served with the Central Gunnery School including TE184 that was allotted to ground instructional and passed to 1855 Squadron ATC at Royton Lancs in 1952. This Spitfire arrived at Royton in standard Silver Aluminium paint finish ( with type D Roundels 🙂 ) and was latterly repainted on site in either a very bright non standard Silver finish or, more probably in my view, White overall.
If this is your Spitfire you may be interested to know it currently flies in Europe and departed the UK a couple of weeks ago bound for the Czech Republic in Otto Smik’s colours with new codes 9N-B.
