Hasselblad A24 220 6x6 Chrome Film Back -Good Seals-
This is the 24 exposure 220 film back for Hasselblad 500 series cameras. 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.
This one is in excellent condition with light wear. Cosmetically it looks great and it functions perfectly. The light seals are good.
The dark slide and takeup spool are included.
