"The documents were so old, however, that they were not listed in the modern computerized library search systems, and some of these documents were out of print." 1
NACA Cleveland library, circa 1945.
Summary
I can usually get even rare and obscure publications through inter-library loan from my public library, but these were reported as having no loanable copies available.
Discussion
I have tried the many excellent search tips at Gwern's Internet Search Tips, and now I am at the "request help" stage.
I would appreciate any help anyone can offer finding them as loanable print copies or digitally.

I requested it through airsciences.org.uk and they sent me a scanned pdf copy (not sharable, so you will have to request your own copy).
