I am selling a very hard-to-find Walz green X1 filter for black and white work. This is the Leica E41 size (41mm). This will fit the 35mm Summilux, the 50mm Summarit, and the 65mm Elmar. This filter size is most definitely not common. The sale includes the original colorful vintage Walz case. The condition is excellent and it is beautifully crafted piece made in Japan.
Price: $40 plus shipping
I can take a personal check (no hold), money order, or cash. Thanks!
