For Sale Scientific Lens Co. Anastigmat #3 (Like a Protar Convertible)

[jimgalli]

IN marvelous shape is this 250mm Sci Fi lens.

It is 4 cemented elements each group like a Zeiss Protar, or perhaps a Plastigmat.

Focal length seems to be 10 3/4" with max aperture f9. Scale is old style US. Shutter works and aperture is perfect. Speeds are off. Maybe if you give the timing piston a clean it'll get closer, but don't count on it. These "double pumper's" are very primitive. Pat. date 1900. Fires reliably and B & T work.

This would make a very viable wide field lens on your 8X10. $225 + shipping
