Oh……I got these image from twitter,and the accompanying article explains that these images are received by the US Army in the wind tunnel laboratory of the Mitsubishi Nagoya plant after the defeat of Japan,and the second one seems like Mitsubishi K7M.Welcome aboard Chaika153,
and are you sure that.they were from Japan ?,I think they are from USA ?.
Thank you so much!The USAF Museum Facebook page bears that out:
