Yes Mark 12, You are nearly right. It is a mark 24 of 80 squadron at Lubeck, probably August 1948, the aircraft is VN307, coded W2 T on air to ground firing practice, note the ammo boxes in the foreground. A Polish pilot, P2 Ossendorf was too enthusiastic and got a canon shell ricochet into his starboard radiator, grounding the aircraft for a few days, I was the engine mech on this aircraft from June 47 untli Jan 50. I was told by a squadron member much later that this Spitfire holds the record for hours flown, I have never gotten round to checking it out with R A F records though. regards.
