Here is my spinoff on kirbyvertibles's Hoover Concept model chart, of every post-1980 Royal all-metal upright (to 1995, before drop-in motor assemblies were used). There are several models that I lack any knowledge, so please excuse me if any years by model are wrong.
1985 and older commercial Royals are identified by a dark blue bag with a red embroidered "Royal" logo (with crown) seen horizontally on top, with "COMMERCIAL" read vertically just below that, forming a "T" shape. The decal on the front of the nozzle, starting in 1985, reads "HEAVY DUTY COMMERCIAL" (red text on silver decal, with red border).
1986-early 87 Royal commercial bags were still dark blue in color, but now had the "Royal Five" patch (name is written five times, white text on clear backing), sandwiched by two red rectangles: the Royal crown logo is on the top red rectangle and the duty rating ("COMMERCIAL") is on the bottom red rectangle. On models made after September 1986, the decal on the front of the nozzle is identified by a marquee of Royal logos (white on black), and below that is the duty rating of "HEAVY DUTY COMMERCIAL" in black on white.
Household models (with some exceptions) made after 9/86 instead had a similar decal used on 1982 and later Prince 501 hand vacuums (a white decal with the company's then-current corporate logo, in dark blue). On all household-type models made after April 1990 (except the 882), a new decal (various colors) was used, which reads "ROYAL - COMMERCIAL QUALITY."
Mid-1987 to 2002 models continued to have the 1986-style logo on the bag, but on commercial models the majority of the outer bags (whether shake-out or with back zipper for disposable bags) were gray in color (some were red or black) and the "Royal Five" portion of the logo is now white on dark blue. The decal on the nozzle is the same. Models with the Adjust-O-Rite, when so specified, were red in color. Between 1988-95 there was also the Duke Series, identified by the red denim bags.
