I recently purchased a set of NIB dough hooks made in England and sold for the model 12 mixer there. In 1976 Sunbeam USA released a version of dough hooks that looked like twisted beaters which proved extremely user unfriendly.
In the bowl are oats, flour, salt, yeast, molasses, powdered milk and warm water. The mixture is combine on low with the bowl selector in the large setting.
It took about 2 minutes form the dough to become smooth and satiny. The hooks provide a lot of harmonic tremer which made the mixer move across the counter. All in all easy, no muss and the guard prevents any dough riding up.
Using the MM with the newer dough hooks it was time to do a sweet dough. Flour, salt and water with yeast allowed to proof. In the cup is warmed butter milk, sugar and egg.
As the gluten forms the dough holds it's shape in a ball. All you have to do is sprinkle a dusting of flour on the bowl as it kneads so the dough ball is free floating. The ball of dough rushes through the hooks and out and then in again. During this time the mixer head goes up with the dough and the crashes down on the bowl. This action often broke the spindle free from the turntable making the bowl impossible to adjust for proper rotation.
