I'm smiling, Paul
Wedgie is fine. I don't know what it's called. I've seen this agitator before in abandonned cottages at Chrystal Beach, Ontario in the 60's in very, very old machines. From the unavailable side-view, you can see three panels going from top to bottom making three wedges or sideways plows. Again, I'd love to see one in action.
Mike, if you're watching, please take one last pic of the Agitator. Just unscrew the cap and pull it out for its beauty shot. Thanks.
