You've got a nice collection of wringer washers there!
I had the round Maytag model E wringer washer. But after giving that one to my aunt, I thought if I ever got another wringer washer, I would want a Maytag model J.
I have a round Maytag with the same red and black agitator in great shape. It has something seized up in the gear case and I am not going to tear it apart. I'll give it to anyone that wants to fix it.
A great variety of models! I love the "activator" agitator in the G.E. Recently, there was a mid-'40s model G.E. on sale locally for $50 that I just missed out on getting. I was so disappointed.
