This is a Hasselblad 12 Chrome 6X6 film Back for the 500 Series cameras.
This back is in excellent working condition and has a matching insert. It has the release switch missing. You can easily move it back and forth with a pen or something similar and it works perfectly. I have priced this low because of this though.
