The old aluminum Gyrators had a wider post than the Bakelite agitators that came later so that would account for the appearance. In later models, only machines with a pump used the strainer, but this machine's drain hose does not have the goose neck or the fitting to attach one so maybe it is a gravity drain.
It is interesting to note the width of the tub around the Gyrator and contrast it to the width of the tub around the Gyrator in the automatics and note how well the wringer Maytags circulated a load in the water and how poorly the Gyrator circulated the load in the automatics, especially in the AMP-style.
