NuTone didn't sell these for very long. With the company based in Cincinnati, you'd think I would have seen one somewhere around here, but never have.
I don't think NuTone manufactured these in their Red Bank Rd. plant, but instead sourced them from outside. I'm thinking it was Hotpoint that made them, but not certain. If I think of it the next time I'm at the downtown library, I'll do some research.
