Hey there Strolly,
Wish I could help. I've got a big bottle of edp from about 5 years ago I think. No idea of its comparison to any other formulations or bottles. Agonizingly right in the place where one has to wonder about it no matter what is to be done. With such a famous classic I imagine one would need to worry about reformulation of each or any concentration. I don't even know how old the edp is as an offering. I'd bet the edt and of course the extrait are closer in history to any real stuff.
