Can you please tell me the name of this iris? #4

Had this iris 2 years also smells like grapes. Please help with a name! Thanks!

at first i thought this was 'Blue Rhythm' Whiting 1945 or 'Seirra Blue' Essig 1932
The more i look at it though because of the more purple than blue overtone and more rounded less historic looking lower beard i think that it is 'Violet Harmony'-Lowry 1948 but i have seen some blue rhythm that can look this same hue/color. this is a hard one

I found out that Violet Harmony does have a faint but nice grape smell too it after viewing some more photos and info..i bet that is it. check this dg photo out..mike
