Speaking of dryer locations in relation to washers, our laundry room always had the dryer to the left. The first dryer was a '63 Westinghouse, with a drop-down door, and it was paired with a '55 Westinghouse washer. The next washer used with that dryer was a '64 Westinghouse FL that had the latch on the right. It wasn't too bad, since the dryer was still the slant-front design. In '73 we got the Maytag set, in which the dryer has the latch on the right, so that worked out well. When I got the new Whirlpool washer, I still used the Maytag dryer, and kept it in the same location. The new laundry room has washer located on the left.
