I found this ?? At an estate sale today. Had to get it as I had not ever seen one before. The lid has a 7. With a 4-4-Q-T and a small 7 under the dash between the 4-Q. Don't see any markings on the bottom, at least until I get it cleaned up. I was only able to upload 1 picture, don't know why. Thanks for the look and help figuring this one out.
