This is nice! What is the maximum aperture of that Wollensak?
It's 3.5.  Originally came, by the way, from a Revere projector with no magazines, and a different lens diameter from the Sawyer projectors I actually have the trays for, so no compunction about taking a hacksaw to the barrel.

Rummaging in the commodious barns I find another, this a Bell and Howell 5 inch 2.8, from an odd combination 8mm and filmstrip projector I stored away but, since I haven't used it in over 30 years I figure it's safe to steal the lens.  This one goes in another scrap mount from a dead zoom,  and with a tiny bit of trimming will go to infinity, but since the sun rarely shines here in January I can't test for interesting outdoor highlights.  Here, however, is how it goes as a macro.  Focused on a rail, with a little contrast and sharpening in post, this one isn't likely to displace the micro Nikkors any time soon, but it might work for portraits.
