Weissenborn are best known as makers of Hawaiian, hollow neck, lap steel guitars. But they have, at various times in their history, produced ukuleles as well. They don't seem to make them any more and they're very hard to get hold of. At the time of writing MGM has one in his store. And that seems to be about it.
But there's nothing to stop us gazing at them. There's an excellent photo of some Weissenborn ukuleles here.
