Question:
I also have a crock type of stoneware that has two type of dispensers coming out of the bottom and it has a diamond in the middle with Perfection Mfg Co. Minn, MN. I saw another person ask about it but didnt see an answer, do you have one? Any direction would be great thanks. Angel

Answer: Angel. a photo of your self drainer would be extremely helpful. Red Wing produced the Success Filter and the Perfection self-drainers. Both of these had the square emblem. Send me a photo – to our executive director, Stacy Wegner director@redwingcollectors.org -so I can better understand your piece and I will try and help you out. Thanks Al Kohlman
