How many Hasselblad's are on the Moon?

Yes, but as indicated above using these cassettes made no sense at Apollo 11.

With later space uses of the 70mm back it may have made sense, with taking one back and several cassettes meaning less volume and weight than several backs.

In later space missions Nasa used 35mm cameras with several type 135 cassettes.

In the soviet missions never 70mm film was used, but rollfilm (likely kind of type 220) and type 135.

Inside the Lunar modual there was a lot of moon dust or dirt being tracked in from out side. Preloaded film backs would help prevent this moon crud getting to the film and inside the film back.

As you, PE and an number of others have pointed out that the engineers working on the Apollo project were knowledgeable and actually knew what they were doing, unlike the fifty-years-later quarterbacks who start from the point of view that they know more in hindsight than the experts at the time.

Who wants a dusty, battered camera, someone already modified...

I agree especially now that one can buy an newer and more advanced model for relatively little money.
