I am being offered a Hasselblad Distagon 50 mm lens, C version.

The serial number is 3879126. I wonder how old this lens may
be. I tried a webpage from a Historical Hasselblad Society, but
the website wasn't working and I didn't get a production year.

The other question I have, I wonder how good the performance of
such a lens may be on both a Hasselblad body, as well as on a dSLR?

Last, but not least, what would be an appropiate price for such a lens.
Please feel free to post a price in your currency.

Thank you in advance, kind regards,
