WTB: Modern 210mm F/5.6 lens for 4x5 format

Hi there, I'm looking for a 210mm F/5.6
taking lens for the 4x5 format. It must be in
excellent shape and be from one of the majour
lens companies and be of a "modern" design,
ie - 6 element plasmat, multicoated. Anything
from Nikon, Rodenstock, or Schnieder will
be fine.

If your selling one of these lenses, drop me a 
line!

thanks

mark
