Here's a picture showing the washer/dryer set. They are from 1963. The dryer is a Deluxe and the washer is either a Deluxe or a Custom Deluxe. 

The 1962-63 models were very similar. As MickeyD said, the 1963 has a different timer knob. the Deluxe and Custom Deluxe models with an "A" suffix had a smaller panel with no provision for a light, the regular Deluxe and Custom Deluxe models without the "A" suffix had a translucent white panel without a light behind it.

At some point during the previous model year (1962), you could get Deluxe washer and dryer models with a fluorescent light behind that panel (models with an "L" like WDL-62, DDL-62 and DDGL-62) but I don't think it happened with 1963 Deluxe or 1962-63 Custom Deluxe models.

BTW MickeyD, did your 1962 Custom Deluxe washer originally had a fluorescent light? My documents don't show it as available on Custom Deluxe washers. What's the model number of your washer?

The fluorescent light was standard in the Imperial and Custom Imperial in 1962-1963 but not available in other models.   Also, there was no Custom Deluxe dryer in 1962-1963 so the 2 speed Custom Deluxe washer (which was otherwise identical to the Deluxe from that year) had to be matched with a Deluxe dryer. 

Here's some pictures from the 1963 Tech Talk manual.

The first one has an error on it, WCD and WCDAR models are reversed but it's how it's shown in the manual. 

Here's one where I corrected the info.

Here's another 1963 model from Canada (it's Paul's WDAC-63). It's the same as the US-made WDA-63 above but it adds the rinse temp selector.

Now the cover of the Tech Talk manual showing the Custom Imperial model with 1962-style timer knob. 

And now an ad showing another 1963 Custom Imperial washer with the same timer knob as other 1963 models.

A video of Ben's 1963 Custom Imperial washer with the later-style knob:

And the early-style Custom Imperial knob again from the 1963 Tech Talk manual (on the WCI and WCIR models). 

Now dryers!

A picture from Ben showing a Custom Imperial dryer with the early-style timer knob. 

The cover page from the Tech Talk showing the dryers. Again the Custom Imperial models show the early-style knob.

Another image from the same manual showing better views of the 1963 dryer control panels. 

More info about the mid-year change for timer knobs. 

Now, 1964 US models that look like Paul's 1963 Canadian model (with the added rinse temp selector). 

Other 1964 models that look like 1963 models...

A suds-saver model 

Note that the shape of the fabrics selector knob is the same as the shape of the timer knobs on this one...

Other earlier additions to the 1963 lineup, with 8 pound tubs...  Again, one that has the rinse temp selector like Paul's Canadian washer. 

You did good! I also added a light bulb in my 1964 Deluxe washer! I'll have to scan some 1962 documents...
