Okay- thanks for backing up my thoughts that this is a conversation starter or a project but not particularly useful for my space or needs. I know it has been in use over the decades it has been here, it's grandfathered in, and it's in a non-residential building so maybe that is why. The last person in the space used it before they left, I think still inside are the cremated remains of a critter who thought it was a good place to spend the winter.
