History of Royal Metal Uprights - Fan Case Housings

[kirbyclassiciii]

It is to be believed that the all-rounded fan case design was used by Royal as late as October of 1984 (I know, because I remember a Royal 880 with a serial of #K84-D-73875, which had the rounded fan case I'm speaking of; "K84" is October 1984). Here is an Electro-Hygiene model 285 dated August 1980.

Note also, in the same picture, that the nozzle design lines around the Adjust-O-Rite opening date from as far back as January 1975, and ran up through the time Royal began revising their nozzle designs again in 2001, when TTI took over.
