For those that don't know and to answer some of the questions I got.
The CF39 is Hasselblads 'open' system. Meaning it uses adapterplates which are available for most camera systems, eg. Contax, Mamiya, V, H and even Rollei.
The CF39 I have for sale has not made more than 15K actuations and is in great shape. I am not forced to sell but would like to so I can generate funds to upgrade one of my other backs to the 39MS, either H3DII39MS or CF39MS (most likely).
The only other brand that has an adapterplate system is Sinar, the only other brand that offers the possibility to upgrade to multishot is Sinar as well.
I am open for reasonable offers and am willing to spend some time with the person that buys my CF to show him how to use this equipment (provided you come here to pick it up).
