Here for sale is my Leica: 21/24/28mm (21-28mm) View Finder. 

Near Mint, in Black Finish.

Genuine Leica.

Perfect to use with all Rangefinder cameras, simply mounts to the camera "hot shoe" mount.

Metal finish, probably the best "value for money" Leica finder you can buy, its all Metal finish is way better than the plastic versions that Leica produces these days.
