Here is a listing of all the pre-1980 Royal all-metal uprights:
--------
ABOUT HOUSEHOLD MODELS
1945-53 models have red bags with gold ROYAL letters/crown with red/black (diagonal sections) metal belt cover (or Adjust-O-Rite) with R-O-Y-A-L letters on black portion and gold crown on red portion.
1953-60 models have red/black bags with red R-O-Y-A-L letters/crown on black portion of bag; metal belt cover (or Adjust-O-Rite) is red/black (half divided) with red R-O-Y-A-L lettering on black half and gold crown on red half.
1961-65 models have red/gray (standard) or red/beige (deluxe) bags with dark red R-O-Y-A-L lettering on red portion of bag; metal belt cover is brushed aluminum with a futuristic-looking "Royal" logo running diagonally up; while those models with the Adjust-O-Rite have white R-O-Y-A-L letters on red (left portion) with the crown logo and "ADJUST-O-RITE" (silver text) on the right portion of plug.
1966-85 models have red crown and R-O-Y-A-L letters on beige (model 801) or light blue (880, 888) bag. The Adjust-O-Rite is the 1960-style design carried over (red plug), but on the 880 and 888 it is colored light blue with red R-O-Y-A-L letters and crown (ADJUST-O-RITE silver text). From 1970-77, the crown and lettering on the bags were outlined.
Starting around 1975, the Adjust-O-Rite plug was redesigned, with the words "Adjust" and "Rite" (or "Adjust-O-Rite" on 1985 and later models, with warning and belt position) comprising the top and bottom halves of the plug (with a line between) in the same font as the then-current Royal logo.
From 1978-85, the bags were redesigned: the crown was the then-current print logo, with big red, futuristic-looking R-O-Y-A-L letters below.

ABOUT COMMERCIAL MODELS
1966-77 models are identified by a dark blue bag (shake-out types have no zipper; zippered bag models, for disposable bags, have a "Z" attached to their model numbers, e.g. 608Z, 611Z) with red ROYAL letters and crown, gray stripes and C-O-M-M-E-R-C-I-A-L letters (red text amid gray border).
1978-85 models are identified by a dark blue bag (both types again available) with then-current Royal logo in red, with C-O-M-M-E-R-C-I-A-L seen vertically below that, forming a "T."
