In 1970 GE began to offer their "HEAVY DUTY 18" washers with a larger washtub. Believe me, I've measured these tubs and don't get too excited because:
<ul>
<li>The V-12's, V-14's and "HEAVY DUTY 16" 's were all the EXACT same size wash tub. GE was lying, shamelessly; you could jam 12 pounds of heavy stuff into those machines and they MIGHT have come clean if there was a spiral activator at home.</li>
<li>The larger capacity machines had a wash-basket that was only <3 inches taller, same diameter, do the math. </li>
<li>The new large capacity machines featured the notorious "Straight-8" activator, which, although lovely to look at, was not a good performer no matter what anyone says. The "Straight-4" was slightly better, but nothing worked as well as those spiral models. The good news is that, because all these machines, in their groups, have identical parts, you can always switch out a straight vaned activator with a spiral one. And I plan to. </li>
<li>The 24" compact Filter-flo's had pretty much the same innards as the standard capacity machines. These were the same marketing oddballs as the old BD Whirlpool 24" washers (which I first saw back in 1972 at the Whirlpool dealer display showroom on West {and I MEAN West} 57th Street in NYC) and still begs the question: Ok, if you could make them smaller with less metal, why didn't you?</li>
<li>I saw a couple of those 24" models growing up because in NYC, even people with enough money to afford a home laundry had space issues. A couple of these 24 inch machines were installed behind bathroom doors with a small fortune paid to a contractor to install hot and cold faucets plus a standpipe. Usually without letting the building board know, so a couple of pay-offs were required.</li>
</ul>
I would plotz if I ever got my hands on a WT3750D. Although I really want that 4-speed WA1250D. Really.
