Some constructive advice: Take off the lens, prism and camera back, and make close ups from the mirror, the inside of the body and the rear. That is what experts - people who might buy such a specialist camera (I once owned one!) are looking at.
The overall condition of your camera will have a strong impact not only on its price but on its sell-ability in general.
And another advice - you might struggle to find a buyer who is interested in buying the whole lot. In the Hasselblad world, there are many legacy owners who are just looking for a particular piece of equipment. So selling all parts individually - including a "naked" body (without prism or film back) might yield better prices and a faster sale.
