OK, I realize this is just kind of a geeky exercise, but I have been going through some old Frigidaire service literature today and am trying to match up the early year's model numbers with years of production.
I did a search to see if anyone had posted a "chart" or list of this stuff and came up with nothing. So...this is what I "think" I know so far.
1947: WJ-60 & WJ-60A
1948: WK-60 & WK-64 (only difference being the timer and fill valve insert)
1949: WL-60 & WL-64 "
1950 & 51: WO-65
1952: WO-65-2
Then I have no information until...
1955: WV-35 (first Pulsamatic) and the unimatic model was?
After that it becomes rather predictable from 1956 through 1958
1956: WS-56 (Super model, Pulsamatic), WD-56 (Deluxe model, Pulsamatic), WI-56 (Imperial model, UNIMATIC)
1957 was identical (the iconic "control tower" model year)
1958 saw the addition of a "Custom Imperial" model in addition to the "Imperial" (both unimatics) and the introduction of a true "suds-saver" system.
Then in 1959 all "home" production machines employed the "Multimatic" transmision and there was the further addition a "Custom Deluxe" model in addition to the "Deluxe" model.
So, can anyone make corrections to what I have above and/or fill in the 1953-55 information?[this post was last edited: 4/23/2012-18:58]
