"I was looking through some WWII American unit histories online and came across this picture you might be interested in the 15th Naval Construction Battalion book that was published shortly after the war. It shows a disassembled Fw190 in a hangar at Tachikawa. It doesn't appear that there are any national insignia on fuselage. I saw your article about the Fw190A-5 that was tested in Japan, and hopefully this sheds more light on the fate of this aircraft. What type of aircraft is in the foreground with the FW190?"
"There are some other interesting images in the book, including some wind tunnel models at Tachikawa."
Thank you so much Joe! Great FW190 photo! It seems there is no tail marking and no clear fuselage hinomaru. If you know the answer to Joe's question leave a comment.
