Nikon PK-11 PK-12 PK-13

Nikon AUTO EXTENSION RING PK-11, PK-12, PK-13.

I am listing these on behalf of my father, a camera enthusiast.

They have been stored in their box, but as you can see in the photos, the box is also damaged and quite old.

Everything shown in the photos is included.
I would be happy if someone could use them.
Thank you for your consideration.
