This interesting photo has been contributed by Mr. Vince Neil from Florida. Vince attached the following comment:
The picture was taken in 1960 while on my first trip to London. And my first thrilling close up glimpse of a Spitfire. As I recall, I stumbled upon this during a stroll around Buckingham Palace and 10 Downing. Also have a shot of a Gladiator at the same site.
Can anyone add something about the aircraft and the occasion? [Vincent D. Neil]
