Wonder Bread Signal Code Dial

We bought this lot of semaphore wheels from one seller. As you can see, they're in pretty bad shape. Only two have both of their tabs, but the colors are still pretty bright. They are 4.25 inches in diameter. We've seen wheels produced by Wonder Bread before. I wonder (heh) if Hostess HQ has a museum that includes all the wheels they've ever made?

The dials don't line up well, anymore, either. It's too bad for me, but I hope some kids had fun with these. I don't know how old these are. 40s? 50s? The Boy Scouts still offer a semaphore and signals badge. They also offer fingerprinting, stamp collecting, and, alarmingly, dentistry. I'd love to see a dentistry wheel, wouldn't you?
