That is a very nice Phrag schlimii.
Ross, the name you are looking for is
Dick Sonnen. Dick lives (or lived?) near Afton, Minnesota, he was a friend of Dr. G.R. "Dick" Clements. Dick Clements passed away in 1990. I believe schlimii 'Afton' is originally a collected plant, Dick Sonnen showed the plant at AOS judging and in shows several times in the 1989 to 1995 time period, I saw it back then. It was not awarded at the time, because AOS judges were using the hybrid labelled Phrag schlimii 'Wilcox' as their standard for what a schlimii should be. Of course time has proven without a doubt that schlimii 'Wilcox' is a hybrid, most likely Cardinale, but it could be Sedenii.
Dick Sonnen also has a clone of Paph micranthum 'Afton' FCC/AOS which was awarded in 1991 at the Chicago Judging Center.
Dick was a friend of Duane McDowel and Arnie Klehm, and if you ever had a chance to meet him, he is a genuine nice guy. I did not have much contact with him, and lost touch with him over 10 years ago. He's worth looking up if you are ever near Afton sometime.
You can see a picture of Dick Sonnen's Paph micranthum 'Afton' FCC/AOS at the IOS website, on the Awards Page dedicated to FCC's awarded at the Chicago Judging center. Here is the image from the IOS.
