You are really the perfume guru! Now, if I could only find a bottle of Sortilege...that is what I hooked my man with...65 years ago!
I have a vintage bottle of that one. Try Ebay-just be careful and ask questions about how it was stored, etc. You don’t want a bottle they picked up from some estate sale, not knowing how it was stored. Also, try the sites which sell decants. There were some sites which sold well-kept vintage bottles of perfume, but most of them seem to be defunct now.
Oh and thank you, but the little I know is just scratching the surface-read some of the perfume blogs like “Base Notes”, or “Grain de Musc”, or “Now Smell This”. There are tons of perfume blogs/review sites out there, the best of them can tell you things like chemical composition, EU/IRFA updates, etc. IOW, they’re better than “OMG I love this new Jennifer Lopez perfume, my boyfriend says I smell like a cookie” lol.
There was an excellent one which was geared towards vintage perfume, but the reviewer (I think he was a Hungarian man training to be a perfumer/chemist) I believe gave up in disgust at the regulations and the generally dismal state of present-day perfumery.
