Linn, the fringe and fleur de lis seemed very 1930s/1940s to me too (I have a 1930s necklace with very similar fringe, and this necklace has a very similar feel/patina to other brass tone jewelry I have from that era). It was the chain that was confusing me. Your chain is different but similar enough that I now feel a little more comfortable dating it to that era.
Cin, I don't smell very well (I have mild allergies, and am always a little stuffed up). I get a slight metallic smell when I smell the necklace.
