leicaman: I knew the head of Hasselblad service USA, Karl Claussen for many years as I was working in the field of astronomy. Karl was present at every launch from Gemini through the Moon missions and he personally inspected all the equipment with the astronauts prior to each mission. We used to talk about all of the Hasselblads that had to be left on the moon's surface due to the LEM's limited thrust and fuel. A number of times while working on projects for NASA I had the specially modified Hasseblad bodies marked FLIGHT in my lab. They are ELMs which had sealed DIN power connectors and large paddle shutter releases for use with space suits... and will as etched glass grids that put index marks on the images for determining scale. I later found out from Karl that some of those bodies went to the moons' surface... where they still sit.. along with my very own fingerprints. They will probably sit there long after man has creased to exist on this planet.No question those missions took place.
"These classic Hasselblads were barely used - a few hundred exposures each, but otherwise are very clean with only some grey dust."
Whoops… didn't notice the 18-300 is a DX lens, my bad.
Ah, so THAT'S why the 28-300 is out of stock everywhere; who's going to buy the 28-300 with the 18-300 available for less?
