Reading those Kirby instruction books has me thinking... did at least one of these prototype Kirby vacuums - as seen in the instruction books - ever exist?
For example: on page 5 of the Kirby Classic (1CR, 1970-73) instruction book, we can see the arm-type speed switch that was officially used on the Classic Omega, Classic III and Tradition. That is prototypical proof right there, because that speed switch didn't actually exist until the Classic Omega (elsewhere in the instructions we can still see the actual "L"-shaped, two-button speed switch). The front wheels in that same picture did, however, make it past the prototype stage.
The front wheels on most pages in the Classic instruction book are prototype. In addition, the "Miracle Head" is called a "fluffer-polisher" according to the belt lifter label (see pages 8 and 18).
