In searching for information to identify many of the aircraft in the Edwin van Opstal collection I am progressively adding to my gallery, I have come across a large number of websites of varying value.
I happened upon one which has a magnificent collection of photos of warbirds, including some very rare flying models, taken at various airshows in the US. The text accompanying the photos is also very informative. Check out this page and the many links scattered throughout the various pages:
