Thanks for the info John!
Gary:
If I've gotten this correct, the brochure shows the newer orbital tranny. (Looks like a horizontal letter "O" in shape).
Therefore the tranny shown in Bobby's picture is the older helical drive.
It seems that for he most part the turquoise agitatior followed the helicals and the white ones the orbitals. In my way of thinking there was no reason to change to the shorter-stroked tranny EXCEPT to facilitate the corkscrew agitator (And/or lower production costs) Of course, the lower end models did not always have one. (As you know from the one you bought and sold).

Clear as mud?
Did I get this right, guys/girls/undecided?
