This was an actual army item. My “Thanksgiving” co-writer Jeff Rendell’s father Ken Rendell has a WWII museum in Mass. and had one of these. It’s a one-shot glove-gun. I believe only about 200 of them were made. Jeff found it at his father’s museum and showed it to Quentin who loved it and wrote this scene into the script.
Nature’s first green is gold Her hardest hue to hold. Her early leaf’s a flower; But only so an hour. Then leaf subsides to leaf. So Eden sank to grief, So dawn goes down to day. Nothing gold can stay.
