Thats a great find Jon and looks like a great restoration too! The water flow thru the agitator is no mistake...its for the filter and that pumping ring is what does the job driving the water thru the slots, into the filter and downward under the washbasket and back up the outer wall and back into the washbasket. I loved watching my aunt's machine when I was a kid. When the motor died, my uncle decided to just get rid of the machine...all it needed was a new motor, everything else was perfect. I hated to see that machine go to the landfill such a waste. I think it was an Imperial model. I remember the panel had numbers for the water temps and speeds and the panel under the controls lit up.
