Hi Sam, Welcome to Automatic Washer!
When you stumble across some of the very first washers--Lee Maxwell has quite a few in his museum-- the variety in agitation methods is really surprising. One type has a three-bladed wooden dolly mounted to the lid, and the dolly looks just like agitator base in your machine, without the center-post, of course.
Wondering if the blades grab and slosh the load or if they create currents to turn the load over. Let us know what the action is like.
When you say you haven't plugged it up to water yet, very rarely do conventionals have an inlet supply or a valve.
A standard automatic supply hose connected to the faucet in the basement sink will do fine, When you get comfortable working with the machine, you can cut the metal fitting off the end of the fill hose and fit it into the drain hose, filling the machine from the bottom. Great fun and almost automatic !
There are quite a few wringer users here who are eager to share their knowledge.
Before I forget: the stainless steel interiors are stunning.
