Gertrude Brown's Mystery Man

On October 4, 2013, I had this photograph analyzed by "Photo Detective" and genealogist, Maureen Taylor in hopes of discovering something I hadn't that would lead me to finding out who this distinguished gentleman is and if he is related to me through my Great Grandmother, Gertrude Helena Brown Smith, who I believe owned this photograph.  Unfortunately, the photograph does not have a photographer's mark on it, which would help us pinpoint the location the photo was taken, but it does have the following writing on the back: 91903, which she confirmed may be a date (September 1903).  That does match the age of the photograph, at least.  It appears this photograph was taken in a Studio.
The first thing she pointed out was the "silvering" that is present on this photo.  When turned at an angle to the light, the edges have a silvery shadow to them.  She said that this was due to the way photographs were processed before 1920.  That silvering will destroy the photograph over time, so she warned that we should have a good scan of it before this happens further.
She mentioned the following:  He is a young man, maybe in his 30's.  He has a tie pin.  He has rings on both pinky fingers and no other rings (not married).  He has very conservative shoes, which she repeated several times.  She found these to be quite distinctive.  He has a pocket watch, which is tucked into his lapel and dropped into his breast pocket.
This man's pose exudes confidence and importance.
That's it.  :(  I am posting it here and at Dead Fred and Ancient Faces, in hopes someone will see it and recognize him or have the same photo in their possession.  Also, praying to Saint Anthony, who always helps me find lost things and this man's identity is definitely lost, at least to me.
