It has been found!
It was upstairs in the garage (yes, The Garage Mahal has an upstairs) in a box. This would indicate that neither Mr. Moon nor I have actually seen it lately, thus proving that we were hallucinating or else we were remembering the sinks in the restroom of El Patron.
Isn't it lovely?
Hurray for Mr. Moon!
As in so many situations, he is my hero.
