May the angels of TV Land look down in your favor for saving this orphan

To think, in a few days this could have been landfill.
My Flash-Matic has a tuner arrangement like that. I don't quite understand what the idea is. On that set it skips channels when you click through so as to put them in order. I think yours is in a different order. I have some knobs in my collection with a similiar arrangement. Somebody must know the answer-inquiring minds!
