Not only the guns but also the accessories, clothing, and books.
Over 20 years ago I visited H&H on Bruton street.
Went with an American colleague while on a business trip; I wanted to look at the books.
Back then they had a great book section with current and old out of print books.
Bought a Robert Ruark book for my son, can't remember which book.
My American friend who owned Ruger .22's had wandered into the gun room.
Found him there talking to a salesman who had handed him a double 470.
American friend asked why bother with 2 barrels when you can use a semi auto.
Salesman reply was polite, and not pretentious.
Great city to visit, have fun.
