These clones are closely modeled after Yellowstone Kelley, and can be found with unusual hair colors. They were made in the 1970s.
Her body is different than a Mattel doll: Her arms are rubbery, like Gumby, almost. Plus her hips are a little wider.
Super Linna dolls have hair that is prone to ratting, like my doll, here. They can often have uneven facial screening--were one eye might be slightly larger than the other.
You can see additional photos of her on Flickr.
