Thanks for the great scans Greg!!!!
So there was a fluid drive as well in that Apex Automatic after all. No one knows for sure but it appears that Apex was producing a Beam style machine with some of their own designed parts like the fiberglass tub with balancing water pockets, etc. concurrently with their own Bouncing Basket design. The 1955 Marquette clearly has gone away from the fiberglass tub for a porcelain tub and the cabinet now is clearly made by Beam as well. Oh so many mysteries!
