The Japanese captured quite a few P-40's. They captured some very wornout B/C's and E's in the Philippines. I have read a story from Air Classics from the late '80's or early '90's about 4 US pilots ferrying 4 wornout P-40's around the Philippines to Clark were they were patched up by the Japanese, and evaluated. The Japanese collected many brand new E's in crates on the docks in Java, that they were even considering using them for home land defense purposes but abandoned the idea. Use Google Images, as there is a color picture of an abandoned E sitting on a Japanese home airfield taken after the Americans had moved in. There is an SBD, I think, next to it with it's distinctive tail. I believe that this colored E was one of three on a freighter that ran the naval blockade of the PI, and were assembled in March, 1942 at Del Monte, Mindanao. They were used until the US quit using Del Monte as a staging base from Australia. As an aside, the Japanese captured 1 B-17D in the PI, and 2 B-17E's from Java, and flew them in Japan evaluating them. In 1945, US intelligence noted from recon photos what looked like a new 4-engined bomber for the Japanese. They scaled out the wingspan to be 104 ft, which is that of the B-17. They never thought that they were captured B-17's at the time.
