I'd add one more thing to the list—the Zippo lighter. This is nothing less than a piece of Americana, and the only reason I don't carry one is because you have to keep them fueled up, and I don't trust myself to remember to do it. Zippos went on the market in 1932, and while they were not an item of issue during World War II, they might have been. Everyone smoked, and I doubt if there was a soldier, sailor, or Marine who didn't have one. As of 2012, when the company celebrated its 80th anniversary, 500,000,000 had been made.
