Asked Hasselblad about this issue last summer: all parts for C-lenses were still available except aperture (sic!) blades, pc-sockets and contacts and some front-lenses. Doesn't sound too bad 25 years after they stopped making them. I would always take that small risk instead of not being able to shoot because I could not afford a CF.
