Updating my own post. After doing all the research and checking I could think of and numerous calls with Gordon, I purchased an HK 94 from him as an initial proof transaction and am now in the middle of another transaction. The HK 94 arrived in perfect condition in as-good or better condition than described.
He has performed flawlessly on his end in all respects and is a tremendously personable and knowledgeable guy.
I am posting this in the event it is helpful for someone else. Happy to be a reference.
