Not quite the same thing, but in the same vane- About 20 yrs. ago at an automobile flea market I bought an owner's manual for a 1939 MG-TA. Inside of it was a receipt for work performed at the MG factory. (It was common back then to send a car back to the factory for routine maintenance)It was dated September, 1940(the heighth of the Battle of Britain). The owner's name was Flying Officer So-and-So, RAF. Scrawled across the face of it was "No charge for work performed. Owner killed in action."
Sent a chill down my spine.
