Actually, rocket78's images (Images 1150791 and 1150792) show a DTP tax code (not a DT one) stamped into the area around the spindle hole, and so they are much later represses from December 30, 1950 - April 15, 1953. The patent text surrounding the entire label margin conforms with a much later release than 1942 as well.
