there are markings on the lenses:
140-150 mm
340-380 mm
500-625 mm
730-969 mm
each lens has a thread for mounting filters.
come from the USSR, I don't know how this lens was used, maybe for photo or microscope or some kind of laboratory instrument.
maybe it can be used for photographing small items, on the last photo (I found on the Internet a photo when these lenses are mounted on the lens Helios-44m), unfortunately I can’t check, I don’t have a camera and such a lens (please look carefully, so that no claims).
diameter landing 53 mm
has a purple enlightenment, condition like new, but there are some specks of dust on the glass.
included leather bag (case)
