A riveted spec tag is a 1976 to late 1978 product. These tags are literally riveted to the cabinet with small, plastic rivets which were originally clear or almost transparent (they can yellow or get cloudy with age). There are two small holes in the cabinet for the rivets.
In 1979 this tag moved up about 3/4 of one inch, and became glued in place, without any holes. There was a small recess in this area of the cabinet to counter-sink the tag. In January 1983 the tag moved to a new counter-sunk area of the lid well --- no more bending and stooping to read the tag.
Correcting James a bit, the Penta-Swirl was available from 1974 to 1981. The earliest versions of the P.S. have five swirled vanes at the skirt, and were available in white for the high-end models such as the 1974 Lady Kenmore, and in gold for a few other models such as the 1974 Kenmore 70 series model. Quickly, the Penta-Swirl mold was modified to add five 1/2" inch tall mini-vanes that span the space in between the vanes, in the shape of a hammock. I don't know how much good these do, but management at Sears or WP must have felt they were worth modifying the agitator molds (which is not a small undertaking).
By 1976 the gold Penta-Swirls were gone and all were white. This agitator was last available in three 1980 Kenmore models, including one with a manual filter (first time ever for that combo of features) but when the tub and basket were re-sized in summer 1981, the Penta-Swirl bid us "good-bye".
The light gray tubs were features of the 1976-1981 upper-end Kenmores, as in better 70-series machines and above. This tub is actually a very light gray / light tan or beige combination. The lower end 70 and below had dark blue and white speckled tubs. Kenmore never made mention of this that I have ever seen, but such was the case for five years until the re-design in 1981.
