Sam Marshall, who wrote the article on what the snorkel colors were, really didn't like the reverse trim models. They weren't cataloged anywhere and, I think, he doubted their authenticity. There are really too many of them to believe someone is turning them out fraudulently, though any brown pocket snorkels are fraud. There are also all of the colors I've heard tell about (but have never seen) sterling, flighter, canary yellow and white - those are the leading candidates anyway. I've a statesman set in reverse trim which is reverse of gold trim (which I know you know). I suppose "reverse" is as good as "opposite" or "alternative" trim. You did a great job on the photo as mine always turn out as silverish or goldish so you just can't tell they are reverse trim.
