This sale is for a mint condition (yes, a mint condition Bronica screen!) Bronica ETRS 135 matte focusing screen – suitable for the four Bronica ETR series cameras (ETR, ETRC, ETRS and ETRSi).
This screen is in mint condition and completely unmarked as far as I can see. This screen is in way better condition than most; you will not find a better one. Cheap because it is the plain matte screen – sorry, no split image screens in this condition.
Try finding another one!
