No, it has been reformulated due to the usual IFRA restrictions. Besides, even the reformulation is quite expensive, as it is now in one of the Guerlain exclusive lines. I have not smelled the modern variety, so I cannot compare. Luca Turin calls it a (good) iris, whereas the original was a very unique combination of violet, herbs, heliotropin, and iris.
Your are right on wanting to try it. It smells like nothing sold today, the style went out of fashion long ago. It is powdery, pale, Luca Turin described this genre as Ophelia, and indeed, it smells very dreamy and a little nostalgic.
Apparently, some BNers here say that in vintage extrait form AO is not too far off l'heure bleue. I have not smelled either extraits, but in edt, they are different, though they both share the heliotropin and a certain dreamy quality. Of course, HB has been reformulated too.
