Hello,
The P-63 photographs were indeed taken at the air show held at Oostmalle in 1996.
And it was Vormezeeles skyraider with which he appeared at almost al air shows held in Belgium at the time. If I can believe his website he has still a sizeable collection.
Skyraider did not do alot for me at the time but I have a little collection now that I will put online somewhere in the future.
Have fun!
