GE V-12s
Very Cool Robert, thanks again for posting this. This is is always fascinating to get this inside engineering information. This type of article offers proof of my assertions that AWs continued to improve in longevity while needing less and less repairs along the way to longer and longer life spans.
Washers and most other major appliances got better and better as the decades when on. You can pretty well assume that washers lasted far longer in the 60s compared to the 50s and continued to get better in the 70s, 80s, 90s and seem to still be improving in the 21st century.
New appliances today still go through a very long and through design and testing process, the current WP BD TL washers were being studied and tested for around 10 years, the Calypso also was in testing and review for at least 10 years, the WP DD washers introduced in 1981 were also in the works by 1972.
There is certainly no dough that Quality Control today is at an all time high in new appliances, cars and just about any other manufactured item you buy today.
