3x Lente Nikon 105 mm poco común, lente Nikon especial, lente proyectora?

There are three Nikon 105mm F8 Lenses in this lot. Not entirely sure what these uncommon Nikon Lenses are used for, but probably as projector lenses?. Internally there are spots of faint fungus and dust, the front and back surfaces have light abrasion mainly on the center.
