One of the items left to me by my Dad is a Nikkor lens holder pictured here. It's made of plastic. The top reads Nikkor and the bottom reads Nippon Kogaku K.K. Japan. Within the case are two rounds of white corrugated and a piece of Styrofoam. There is no part number on it anywhere.
Does anyone know if it sold with a lens and if so, was it a specific one? No lens came in it, but my brother has my Dad's c. 1970s Nikkor 43-86mm and I'm wondering if this holder is for that lens. Thanks for your help.
