Hasselblad A24 220 6x6 Black Film Back -Matching Serial Numbers, New 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 36 exposure 35mm through a Hasselblad.
This one is in excellent condition with light wear. Cosmetically it looks good and it functions perfectly. Our technichian has replaced the light seals, a $75 value.
The serial numbers match. The dark slide and takeup spool are included. This is a nice one.
