J.J. -
All of the postwar German and Japanese technical material processed by or published by the T-2 technical intelligence people at Wright-Patterson eventually ended up with NASM at Suitland, Maryland. A couple of years ago they moved to the new museum in suburban Virginia. So you should e-mail them and see if they have it.
