Nikkor 3.5cmmm f1.8 (L) Lens Hood Nippon Kogaku plastic version boxed very rare

Dedicated plastic lens hood for the W-Nikkor 35mm f/1.8 in Leica screw mount (L39).

This hood uses a different filter thread than the hood for the Nikkor 35mm f/1.8 in Nikon S-mount, so they are not interchangeable.

The 35mm f/1.8 L-mount lens itself is already quite rare and difficult to find, but this original plastic hood is even rarer and very seldom seen on the market.
