Here's a wheel that was produced by a company that still exists! The Phonetic Word Wheel is quite large: 11 inches. The instructions say:
Interest is stimulated by the competitive or game element among children, e.g., the number of Jack word vs. the Dick words. Handled wisely it offers as much enjoyment as instruction, further details of which are left to the ingenuity of teachers and parents.
But it who wants to use it wisely? You can make all kinds of fun words with this, like flern, brickle, zopped,play, and queach.
This is wheel is in pretty good shape except for where someone slapped a big piece of cellophane tape across the back.
