While on eBay, I accidentally woulnd up in the darkroom category. Oh well, sometimes something interesting shows up there, so I enered "lens". In many times searching there, I have never failed to find at least one taking lens. (Occasionally, even a lens in shutter shows up as an "enlarging" lens.) This time there several, including one weirdo. This was listed as a "Polexar" Hypergon Topogon copy. Well. it couldn't be both, but it does look like an extreme wide angle, with a protruding rear element.
Further details are that it is an f9 210mm made by "PZO". The Lens Collector's Vade Mecum gives the maker's name in full as Polskie Zaklady Optyczne but has nothing to say about this lens. As is regrettably usual, it has no flange. There is a front lenscap, but no rear lenscap, which in this case would be more important. It apparently has a diaphragm, because one photograph shows markings from 9 to 22.
Not being either wealthy or an ULF person, I am not going to bid (starting at $199) to satisfy my curiosity about this item, but am hoping that someone on the Forum will have some knowledge of what must surely be one of the most obscure lenses.
