Here's where the 'permanently closed' comment may have come from. You'll get this if you google 'D Henry Gunmakers Bentley'. Other searches may provide the same result.
Hunter Guy was providing info that is available online. Don't think he was trying to cause trouble.
I first used David Henry many years ago when he had a storefront in Bentley. After he had a break-in, he closed the storefront. I am quite sure that I found him all those years ago via his website. IIRC he also had a small retail section.
Good gunsmith, by the way.
