Our family doctor here in St. Louis told me when I was a teenager in the '60s that he had been involved in the development of the .60 cal. machine gun round during WWII. In his office he had this Winchester box sitting on display on his book shelf. After drooling over it long enough, he gave it to me. He told me it was presented to him by Winchester. He also had a couple of the .60 cal. rounds. You can find them sometimes here in St. Louis. I know there were larger Winchester display boards, but does anyone have similar Winchester displays centered on military cartridges? The display is still in very good condition, though I had to replaced the black elastic ten years ago as it had deteriorated badly. Notice the label indicates Winchester Repeating Arms Company, Division of Western Cartridge Company.Would this be a pre-WWII label used for the wartime display?
