Update:
The last cryptic (soft of) message I received from the professional researcher seems to indicate he found the insignia in a book called "Order of battle, U.S. Army, World War II by Shelby Stanton that indicated it was the 31st ID crest. At least that's my interpretation of what he wrote...
I have asked him if he could scan that page and PDF it to me...but I have not heard back.
