You are bidding on a lot of three Nikon accessories.
The first is a coupler for flash gun in original box.
The second is a Nikkor -Auto rear cap in original box. The box is damaged.
Last is a Nikon Focusing Screen Type B it its original box. The protective packing foam is so old it is crumbling.
Each has the Nikon F design on the boxes. The Nikkor-Auto has a tear to the end flap. It is not known whether any of the pieces were ever used.
