Do you know the origin of it or any history.
To me it looks like a scanning lens from a photo typesetter. A modulated laser beam is scanned by mirror onto photographic film. The film was used as a negative to make a printing plate. Most of these units have been replaced with ComputertoPlate equipment that scans the printing plate directly. New England USA was an area which manufactured this type of equipment. This piece of optics would been very expensive when new.
I used to work on this type of equipment 20 years ago.
