I was just looking at the Warbird Registry and was supprised at the number of significant aircraft that have slipped off the radar over the years, I have also noted this whilst reading old magazines etc. I know that some of those aircraft have been scrapped and no doubt some have crashed.
What I like to know is, based on what you know, would you say that it is fair to assume that the majority of these aircraft still exist (hidden away in an old hanger by a secretive collector etc.) or is it safe to say they no longer exist?
For example;

http://www.warbirdregistry.org/p47registry/p47-4222504.html
http://www.warbirdregistry.org/p51registry/p51-4484857.html
http://www.warbirdregistry.org/mossieregistry/mossie-n1203v.html
http://www.warbirdregistry.org/b25registry/b25-4232479.html

I'm not talking about just these a/c I am just using them to illustrate my point.
