I am hanging fire over a Givenchy III with broken atomiser...how are you getting at your YD? Does it just unscrew? And then you use it like a splash bottle?
Vintage formulas I love, off the top of my head: Bandit, Vent Vert, Ysatis, Caleche, virtually anything by Coty, or Goya. Calandre, old Rive Gauche (PP Rive Gauche smells more like vintage RG than new RG) aforementioned Givenchy III, Dioressence, Diorella, (Miss Dior herself hasn't changed that much I don't think, oddly, but those two have) Je Reviens, Blue Grass, the old Faberge' perfumes, the Houbigants (esp Chantilly, Mystere de Rochas, Ma Griffe, Fidji, Heaven Scent...
They have all been reformulated - some out of all recognition (Blue Grass etc) Some are lovely in the modern version but without that "Wow, what the hell was that" va-va-voom of the old version.
I am hoovering up the old Ysatis on ebay. I have more than enough to last me till the end of my days I think, but it is so epochal (at least for me) and the new version is just so meh that I need it all!
