I just noticed something interesting! The side art of the left side of the machine shows "Little Nellie" autogyro being attacked by Brantly B2B helicopters. This is totally incorrect. The B2B was used by Osato in You Only Live Twice when he landed at his business and in search for Bond a Pussy Galore in Goldfinger. The B2B was never used in any attack scenes. It was the Bell 47 that was used. I wonder if they couldn't get right for the Bell 47??
