hi pat, you didn't suggest if you'd mind oldish designs ..

probably a longish verito ( 14.5 or 18" ) with the element removed.
its based on a rapid rectalinaer design so stopped down is sharp.
one of reinhold's wollaston meniscus lenses in a barrel w/waterhouse stops will probably cover it too
they cost much less than the other lenses mentioned , have a large image circle, and stopped down can be pretty un-diffuse/soft.
