This vintage Keihan Opt. Proskar 1:4.5 F=21cm lens w/ Packard Ideal Shutter on 5.5x5.5" Board appear to be in excellent cosmetic condition, the glass is clean and clear with no scratches, fungus or haze, only thing is one layer on the inside element some coating missing when I tried to clean it(see last picture), if you have a chance to polish and re-coating, it would be perfect. the packard ideal shutter should be in working order but there's no air bulb comes with it, untested, but it can be opened and closed.
This is an amazing Large Format fast lens, which offers a massive image circle which will cover 5X7 and more.
This lens has 15 aperture blades moving smoothly, weight 11.5 oz.
