I feel like I am monopolizing pass the samples. Unfortunately, I cannot be of great help here, because I am a recent aficionado, having started a few years ago in an era when Mysore sandalwood was already off limits. So I wouldn't really be able to comment on true sandalwood. That said, I'd like to smell the vial, for my curiosity.
I have a few vintage perfumes, but cannot think of any where sandalwood is really prominent. though, again, I may not be able to say even if it's there, mistaking it for woods or what else.
