Tom,
Those Kirby machines that did have the 13" nozzle originally will also have a shaved headlight cap casting, in order to make the cap fit correctly against the 13" nozzle.
I have seen 13" nozzles on machines that were designed for the 16" nozzle, so the (unshaved) headlight caps will not go down all the way toward the smaller nozzle.
Others have also shaved the 13" nozzles to make the standard-issue light caps (for 16" nozzle) fit against them, but shaving the nozzle castings to make them jibe with the light caps (16" nozzle) is not a good thing because of the rarity of these smaller nozzles.
