[Sean Keen]

Hi there

I have found this lens and have no idea what i can get out of it, of course i can make a Pl mount and try in on camera , but trying to save some cash for my scarlet w

here the details
F=100mm
T=2.5-16
focus from 1.25 - 2 m no infinity max 2 meters

have several mirrors inside

as you can see some sort of knob on top, if I move it the mirrors moving clockwise or anticlockwise

As me and my friend think, this is most probably a vario-anamorphic lens, like a Panavision Super Panatar.

Thanks a LOT for you interest , but the image comes not ellipse, i see the image not in focus and all small lights are round, I do have similar ana lens this maybe similar to Panavision, please have a look

Well, maybe the lens in set right now to produce a 1:1 image? Try turning the knobs and rotating the mirrors, does it change anything? Also, the bokeh is always round, as it gets the shape of the aperture, it only gets ellipse shaped after the image is widened in post. This lens looks very unique though, and is worth closer inspection.
The second lens looks sized as a 350/750 okc? But the knobs and the lens overall looks a bit strange to me.
We could continue our talk in russian, chatting, if you can.
