This is the late model film back for the electronic cameras. The big difference is that it communicates ISO to the body. It also works on mechanical cameras like the 500cm.
Note that 220 is no longer widely available but you can still find some expired on eBay. I've also heard of people using the A24 back and a conversion kit to shoot 35mm through a Hasselblad.
It is in excellent- condition with light wear and works perfectly. The mechanical movements are smooth and the light seals are in good condition.
The dark slide and takeup spool are included.
