This sale is for a mint condition and probably unused genuine Bronica GS-1 Focus Screen Matte for use with the GS-1 camera. It has no signs of use.
This screen is boxed (but in the wrong multiformat screen box). It was probably pulled from a new camera and has sat in this box ever since. It is basically new.
An extremely rare item – try finding another one. Then try finding a perfect condition screen – you won’t find one.
