Value of 305mm f/9 Graphic Kowa?
 

I have one of these lenses and am considering putting it on eBay.
It would be nice if I had some idea of its value in advance.

The glass is excellent with no marks, scratches, fungus, or
separation, just a little internal dust that can probably be cleaned
when it's mounted in a shutter. There's a small dent in the front
filter mounting area that is easily repaired by someone with the
proper tools and skill. Physical cosmetics are excellent.

Please reply to the group.

Many thanks.

Steve
