thanks for the ping! And WOW to the detective work in this great thread! Since there weren’t many scenes of formal surrender by the Japanese, because they fought until incapacitated or killed, the best guess is, the surrender scene was due to the overall national surrender announced by Emperor Hirohito, thus the scene was somewhere such as Okinawa where the Japanese were still fighting at the end.
Funny, I have had these pictures for a few years, and while cleaning the other day, I came across them and took a closer look at them.
Interesting stuff, indeed.
