I was browsing threw ebay today and came across this lens which looked quite interesting

Has anyone seen this before?

Looks multi coated. Serial number is new, this could be a prototype. Also, it looks like there is no aperture control.

I am irrationally nervous about buying camera gear from Poland.

Just doesn't look right to me. The rear shows RF coupling without a secondary helical. The distance markings seem too widely spaced to me for such a WA lens. I don't have anything wider than 40mm with me and these are definitely wider spaced than that - suggests longer focal length.

Why is the box pristine and the barrel marked?

Looks to me like a cut-down Jupiter-8 barrel.

I can't find any internet references to a Xenon 30mm. There is a reference to a Xenogon 30mm F3.5.

My bet is "fake."

There is a samsung NX lens that fits these specs.

Maybe, if you were lucky, that would be the donor lens.

The mount is definitely a Jupiter 8. Matches my 1967 J-8 almost exactly. Distance markings exactly match. So whatever it might do on a mirrorless body it is useless for RF or zone focus.

Whatever it may be, it has been mounted in some old FSU barrel - the box and lens positively are from a very different period.

A aperture-less 30mm f/2 Cine Xenon used to be sold for a variety of small format cine/video projection applications in the eighties/nineties, and perhaps past that as a CCTV (surveillance) lens - so it will probably something from that lens family. If so, it may not even cover M4/3 at infinity, and certainly will not cover 24x36mm (even more so as it can't be stopped down).

The box also looks like it's been fashioned to fit the lens...
