Thank you Manfred! These are different lenses. Mine has no aperture, no focusing.

I think this Biotar might be in original factory shape,
same story happened to me, when i've found old 1.5/35mm kinoplasmat from Hugo Meyer, it was just a lens head without helicoid.
But Your's missing aperture.
p.s. lens part of Night Exakta?

I think all lenses what made for camera at least have aperture, but if we start from Olympic Sonnar 18cm logic where is aperture behind last rare element might be possible this is a lens part. I think a movie camera sound is more logical or some industrial tool.

Yes, as I say, with some television/movie cameras, Iris is part of camera body, not lens.
