Underwood Hifi / Underwood Wally...

 Carl, My guess is
 The Man can list 500 products.   When a customer calls and wants something.  The Man just calls the maker.  Maker then ships it off to customer.   But Do what ever you can to Dodge shipping back anything to the man with the 500 item's  

Walter is a wonderful old school salesman. What I mean by that is that he is honest and he has integrity. In other words if he describes a product as having specific characteristics it does. I contacted him a few years ago when i was doing some CD reviews for PBS and asked him for a educational discount. He was such a gentleman and said of course. I would not hesitate to purchase any gear form him. One point aside he is also fun to talk to about audio history!!!!

I'm sorry, this subject goes through my head every night in bed. It isn't Underwood HiFi you need worry about, it's some of these vultures right here on Agon. Mid to late 2000's, purchased a Bel Canto DAC that I had spoken to Wally about. I don't even know if he still does his mod's, but back then he thought a lot of that little Bel Canto piece and had 4 levels of upgrades. So I bought it and sent it to Wally. Sent it back ASAP and WOW, this was a different piece of equipment.... Well done!
So that was during a buy, sell, buy period; so I listed it here on Agon for I think a whopping $400. Guy buys it and contacts me and says did you open this at anytime.... there is a screw loose and I'm letting you know before I open it. 
Long story short, there was a loose screw, and he railed at me... Do you know what could happen????? I offered his money back, but he just acted like I had purposely sent him a Dirty Bomb???? 
I told him I apologized and told him I was refunding his money AND he could keep the DAC as well.
Conclusion? Don't believe all you read here.

Interesting responses.  Some are eye opening.  Walter/Underwood is no doubt a good longstanding retailer.  Thanks again for all the input.
