I tried a Google search for "Mcnally submissions on chipguide" and didn't get a cohesive list or grid like yours.

I think you meant to use Google's A.I. mode to generate the grid that you found, not the general Google search. I did not try that because I can't risk using A.I. services on my computer (since they then search your hard drive to contribute to their knowledge base, and won't allow that because it would expose clients' confidential data)
