Did they also make a "Cataractor" with a milky white filter between the elements?
Maybe, maybe
Today I've got the beast - and it's amazing
It's fitted in a very special heavy brass body, with 25-lamelle iris up to f/4 (!!), and a three-blade "shutter" between the lenses, operated by a rather big handle outside. It's Glaucar-Anastigmat 80/2, yes, and it has an unusual optical scheme - a cemented front lens, and four (?) lenses after it. Ewww. A nice paperweight, or a gift for a collector.
The good news also is that I've got a very clean 135/6.3 Tessar, made in 1912 judging by its serial number, fitted in
almost working Compound 00... he-he, is this lens worthy repairing the shutter? Perhaps yes, that's a very very early one...
Cheers,
Zhenya
