I picked this up at a junk shop for $1.00 It measures 6 3/4 at the base, and is 10 1/4 tall. The reason I grabed it, is it has a Blue Jean Seam on the inside. My first one. I'm guessing it is a Thomas. I am putting a few possible numbers on it - M-4415, M-4415A, M-4420, M-4422. All have a hidden bottom skirt with these deminsions... Does anybody have any input ? Tracy
