The fact of Shelby searching is recorded in "Rikugun Genyou Shisakuki Shouko Meishou Ichiranhyou".
It means "Army Modern Experimental Planes Call Name List" in Japanese language.
All Japanese planes of what equipped to call what name are written in this document.
That was made by the Army aircraft head office on February 25, 1945.

I had my friend investigate it. In 1975, this document was recorded in a document about weapon production and supplement of the army. And that was kept in "Japan National Diet Library" in Tokyo.
It's also kept there today.

A book of Bunrindo of 1990 year edition is written in that referred to that document.
(It's written in P.36)
