My buddy showed me this photo last week of the goggles his dad was wearing along with his flak helmet. Lt Alan Gould was a B17 bombardier with the 338th Bomb Squadron, 96th Bomb group. You can see a slight dent near the right bridge of the nose. An 8 mm round took out the right lens and was recovered in his helmet. Good illustration of what you see in that old trailer. They will eventually be donated to a museum.
