Pare a fi obiectiv de proiector cu deschidere la 90 de grade.

The other 210mm Poloxer Ernest asks about, with a maximum opening of f/9, is a symmetric wide angle process lens of double Gauss construction similar to Schneiders G-Claron WA, or the Process Nikkors from Nikon. At present, this is the only process lens of this type made in the Eastern Block that I am aware of. PZO also made enlarging lenses (trade names Amar, Mikar, Janpol), but so far I’ve only seen 35mm and medium format versions. PZO is in existence today, but does not produce LF-related equipment. The Hypergon comparison in the ad is obviously wrong, and the angle of coverage is probably about 90° given its construction and use. Since its a process lens, its usefulness for infinity maybe doubtful, given the reports about G-Claron WA's.
