The rarest.. This is the only Japanese Zero (this one is an A6M5) left from WW2 that still flies using it's original engine. THE ONLY ONE. It was captured in the Marshall islands and was brought to the USA to evaluate it.. It was even flown by Charles Lindburgh!
This plane was used in about 10 movies (pearl harbor, Tora Tora Tora ect..) and counting..
I've got a ton of photos from Planes of Fame in Chino California if anyone's interested.
