Robert,
I recently received a case of Jack Ross 9mm reloads. Always the curious, I checked all the head stamps and found 25 different stamps. Some quick searches provided volumes of information on head stamps and their origins. Attached is a scan of the case and separate case list. [Click on image to embiggify.]

P.S. I couldn’t identify seven of the cases. They are blank.
