There is a term used in the antique business provenance. Fom the French provenir, "to come from", ahd refers to the chronology of the ownership, custody or location of a historical object. It is very important and seriously effects the value of an item. If the seller cannot provide you with this documented information then do not buy
This is a picture of me holding the camera used by John Glenn in his first flight. I am standing next to the camera engineer who designed and made the modifications.
I can say that these were not trivial as noted in the Photo Net listing. These were made by hand back in those days.
In the background are 2 capsules for the next launches. The one in the foreground is Liberty Bell 7. I later went into the clean room and got to inspect the capsule.
The camera engineer is still with us today and is living in central FL. The camera is "supposed" to be in the Smithsonian.
The names of all of the workers are engraved on the inside of the camera that is there.
Great photo! The more I think of those guys climbing into those aluminum cans set atop thousands of pounds of liquid hydrogen and LOX, the more I am impressed by their bravery. Each one was a Lindbergh.
I wonder if these cameras would work any better than the regular version or they may be worse. Definitely, no better than a regular camera of same model if we use them on earth.
The capsules were honeycomb Titanium with thin sheets of Titanium welded to each side of the honeycomb. The walls were about 2 cm thick and when you rapped on it, it was as solid as rock. No ring, no metal sound, no hollow sound. The sound was like knocking on a rock!
The inside was a control panel (mostly indicator lights) and a seat. You just went for a ride.
I have some souvenirs of the launch, and AFAIK, my name was the last to sign out before the launch and the first to sign in. The pad was still steaming.
