A friend of mine receive 2 Hasselblad camera:
a 500 C/M with a Carl Zeis 80mm f2.8
a 2000FCW with a Carl Zeis 110mm F2
there is also a few filters and what looks like extension tubes, there is an extra back too.

She would like me to sell them for her, but I have no idea what I am really selling. I can go to eBay and sell them there, but I think it could be interesting to learn about them from you guys. So before selling them, what do I need to look at?

Thank you,
