Please forgive me, I've searched the net for days, trying to find some information about my Nikkor 760mm process lens. I had the lens mounted in shutter by SK Grimes, but almost never use it. I intend to sell this lens on eBay in a week or so, and am writing the description for it. I would like to add some tech details. Does anybody have some info I can use, or point me to a link, where I can do some research. I'm particurally interested in the coverage of the lens (IC). Also, do you have any idea of the value of a Nikkor 760mm, f11 mounted in an Acme#5 shutter. The lens is in perfect condition.

thank you
