Reversible Double Shell Stitch Crochet Pattern?

Does anybody have the old LEE WARDS pattern for a REVERSIBLE DOUBLE SHELL CROCHET STITCH? I am trying to crochet with this stitch and can't find it anywhere, at least not that same one. Using two colors of yarn, one side looks like color A with color B as the background and when you flip the afghan over, the main color is B with A as the background color. It's really a very wicked cool looking stitch so if anyone has it, I'd really appreciate if you could tell me in which site I could find that.
