Sorry! I know what you mean about ignorance. If they're out there, I want them. Also, I should add that the number in Dusk series depends on what you include as Dusk. Those with the numbers 3538 are definitely Dusk (there are five shapes here), but 3595 is also considered Dusk by some. And there are others. A consolation for me is that there are enough around to make it possible to collect them, they can be found for relatively low amounts on occasion (when I buy them), and yet they're very attractive, imho. Good luck.
