Pyrex Blue diamond mixing bowl

. This is an unmarked Pyrex bowl in the 2.5 quart #403 size. This piece has been recently found to be confirmed as the "Dainty Maid" pattern that was sold as a piece produced by Pyrex but sold unmarked by several stores during the mid 1950s. It is the identical shape and size of a Pyrex 403 (8 5/8" across, and 4 1/8" tall, 2.5 quarts) No chips or cracks in excellent vintage condition.
