Here is a link to W. Milton Farrow.
http://cap-n-ball.com/farrow.htm He was a sales rep for Marlin and became famous shooting the Ballard rifle. He won many important matches in America and Europe shooting Ballard's. He then went on his own with a unique single shot of his own design. Few were ever built and most are unique specimens. It appears he moved and tried at a lot of locations with little success. I have a original advertisement brochure he had printed that I can send you a picture of if it helps. It is only about his rifle, loading tools and sights.
