If it's a TB, it may be Mystic Lover (G. Sutton 2000).
Here is a photo of mine last year.

oh thank you so much, i think you are dead on! i just looked up loads of pics, i thought my standard was not white, but its so heavily veined in the cold weather i am sure you are right. i knew this couldn't be hard, and i thought it was suttons, but didn't have much luck poking around on my own with no hint! thank you, i am thrilled, this was from a friend and it truly wowed me when it opened, i think its stunning with the yellow beard, my fav colors too! thanks again~

You're very welcome. It's nice to be able to help out sometimes. I'm normally the one asking for help. :o]
I thought it looked dead-on too.
I'll agree about the white standards. I wouldn't have called mine white either... But then it was a first year bloom.
