Up for sale is a used Nikon Nippon Kogaku L-F lens adapter in excellent used condition. The adapter has some visual blemishes as photographed, but the rotation is smooth, the locking mechanism operates well, and the threads and bayonet mount are both in excellent shape.
This adapter is ready to use!
These are very rare and hard to find. Most likely this one was manufactured in the late 1950's or early 1960's.
Please check my feedback and contact me with any questions!
