Here today is a vintage mixing bowl marked on the bottom stoneware USA.  I believe it to be a Watt piece. Looks like it has the number 65 in the middle.  Bowl does have some condition issues. Has a chip out of the edge. Some discoloration spots inside the bowl.  Measures 9 inches across and 6 inches deep. Age is unknown. See photos and ask any questions. I do my best to describe all items. Sometimes I miss things.. Please Please ask questions. Thanks for bidding and good luck. Check out all my items for some great finds. Lots of cool stuff at my sales. I can combine shipping on most.
