I was reading Andy Yoder's blog last night. He recently bought three antique radios. Their wasn't a knob to be found on them.
What I found particularly odd, from perusing police and press reports, is missing radio knobs have become common in your old environs. It's even happened to me. I came home roughly four months ago to find the passband knob for my Drake R-4 gone and a sour, moldy odor in the room.
Get help, Al, before we have to do another intervention.
