Originally reproduced by Mike Wald of Des Moines. He made both pieces. He quit making them about the time Ron Scobie started masking them. Ron still shows one of the pieces on his website.
Mike has mentioned many times that he might make them again, but I doubt he will, not worth the time and investment, they require a lot of work the way he made them. His were ready to install when you got them.
