So I picked up those 70mm Hasselblad backs that were for sale here in the classifieds and wondered a few things.

Other than NOS on eBay, is anyone still producing 70mm? I assume the backs take perfed 70mm, rather than non perfed? Finally (and most importantly) - how will I load the darn things? Is there such a thing as a bulk 70mm loader? Once loaded and exposed, I assume there is a special developing tank?

Sorry for all the questions - just figured this would be the place to ask and get right answers...
