Apollo 4 and 6 each carried a pair of high-speed cameras on the second stage of the Saturn V launch vehicle. They filmed the separation of the first stage and its interstage ring, after which the capsules containing the cameras were ejected, splashed down in the ocean, and recovered. Footage from these cameras is often used in documentaries.
What did these camera capsules look like? Photographs before or after the mission, or drawings are acceptable.
