Tut was a vintage string instrument collector and one of the founders of GTR guitar shop in Nashville, now known as Gruhn Guitars.  John Hartford called Tut "The King of the Horse Traders" because his instrument collection was so vast.  At one time Tut owned 67 Dobros and many other fretted string instruments.  He bought, sold, and traded many instruments over his life.  He was always searching for rare and better sounding instruments.  Here are some old photos of his instrument collection and music room.
