My FINAL update...I got a full refund check in the mail on Friday Aug 16, 2019, so my dealings with Pat Walsh are 100% done (two years later). I can't tell you how many phone and email messages I left him, but I guess they paid off.
He did write a cryptic note with the check that said said "he had been in a crash in 2017".
My warning to others would be to only do business with him if it's a "in person, cash and carry" deal.
