I don't know this fragrance first hand, but according to Perfume Intelligence, the original Mila Schon debuted in 1981. It was later discontinued and relaunched in 1997. Then that version was discontinued in 2001 and reformulated in 2002.
Perfume Intelligence has this to say: "In association with Morris; a floral-mossy chypre edt with top notes of bergamot and cloves, heart notes of jasmine, acacia and patchouli on base notes of vetiver and amber."
I have no idea how closely the latest version resembles the original.
