On models that used more than one version of a rug nozzle casting throughout its sales history, such as the Heritage II, is it true that the earlier-production nozzles for that particular model are obsoleted as soon as the newer type goes into production?
Example 1: Heritage II 2HD. The original standard (16" wide) HII nozzle casting was similar to the first Heritage nozzle, but switched to the shaved version in mid-1985, and was given the BPI light the following year. Therefore, if I am saying all this correctly, any previous complete nozzle (less brush and belt) are obsoleted when an improved version goes into production.
Example 2: Heritage 1HD. Some of the (standard 16" wide) nozzle castings still had the attaching holes for the Shag King and, as a result, that attachment was still available briefly (but was not made mention of even in the original 1981-printed instruction book), but most examples did not have the holes on the casting. I'm wondering, wouldn't these nozzle castings (with the holes) still have had the old-style rug plate hinges (those going back to the 1970 Classic) rather than the 180-degree latches that most Heritage nozzle castings used?
