Mr. Stewart worked for several major companies and designed many of their top models. He designed the Damon Howatt Hunter, Eldorado,and Diablo.
While working with Bear, he designed the Kodiak Magnum, Kodiak Hunter, Tamerlane and had a big part in designing Fred's famous takedown.
I believe he worked for Wing and Duke Savora before going on his own.
Bill is one of the most under-rated designers/bowyers that ever lived and has never gotten the credit he really deserves.
