That's a very nice set of Maytag's you've got there. I hope you're planning on keeping them. Just for the sake of interest, the dryer model number you gave us(PDE701) means pink dryer electric, model 701. Had this dryer used gas as its heat source, the model number would've been PDG701. The serial number indicates that it was built in February 1962.
The washer model number(PA700) means pink automatic washer, model 700. Its serial number ending in CX, indicates that it was built in October of 1961.
I actually have this same set in yellow,(though my dryer is a gas model)and my washer was actually built in the same month and year as your dryer. This washer has a lint filter agitator that predates the built in fabric softener dispenser, so you may want to look around for the separate fabric softener dispenser that was designed for use on this model. There's a good chance your grandparents would have bought it along with the machines way back when. For all I know the washer may even have come with it. They're very hard to come by today, so make sure it's not being tossed out simply because nobody knows what it is. It'll look like a white plastic bowl with the numbers 2-1380 embossed on it, and it will fit on top of your agitator.
