We might pull it off with a few caveat's you'll have to live with. Just a couple of little tiny items.
Like, it doesn't say Cooke on it any place. But I have other Xerox lenses that do have the Cooke name on them, so we know Cooke was under contract to build Xerox lenses.
Also note it has no flange or threads for one. The enterprising person will figure out some way to mount this beast. Maybe you could drill the clunky aperture rotation device and use it as the flange, turning the whole lens assembly to close the aperture.
It's definitely an f5.6 triplet and as such should produce some very very fine portraits on 8X10 or smaller.
$85 plus $12 for a flat rate medium box in USA.
Small print: Whether or not this is actually made by cooke is of course 60% conjecture and 40% edumacated guess.
