Smithsonian National Air and Space Museum Package Received

I received a requested package from the Smithsonian National Air and Space Museum.  It is a listing of the historical information they hold on the Junior.  I will be ordering some of the drawings at a future date. Help!! Some of the drawings listed on the NASM report are from the 1970s and include the name “Nelson.”  Does anyone know about these later drawings?  The package also contained a copy of an article published by Paul R. Matt on the Curtiss Wright Junior CW-1 published in Historical Aviation Album No. 11 June 1972.
