Time to dust off the original parts books...
Interesting!
It appears that '56 and '57 do have separate caps, per the original parts lists that came out each year for those washers.
Imperial & Custom Imperial caps:
WO-65-2 (1952-1954) - 5433707 (Code 253, 1958 parts list)
WV-65 (1955) - 5433707 (Code 10)
WI-56 - 5435204 (Code 10)
WDU/WI-57 - 5436906 (Code 12)
WI/WCI-58 - 5437855 (Code 253)
All 1959 -6565033 (Code 9.376)
All 1960 - 6566814 (Code 9.376)
All 1961 - 6566814 (they apparently recycled the PN, but the cap logo changed in '61) (Code 9.376)
All 1962 - 6566814 (Code 9.376)
Later editions of the SER-723 washer parts book, starting even for the 1958 models as seen in the photos below, group the '57 and '58 caps as being the same item: 5437855. Now we know with certainty the difference between 56/57/58!
This is the first time I've seen the original '57 cap. Very cool! the nubs are meant to hold the bleach dispenser in place.
Bud - so happy someone was able to supply an original '57 cap!
