This sale is for an very rare, used but still excellent condition Bronica SQ split image / microprism focusing screen – suitable for all Bronica SQ series cameras (SQ, SQ-A, SQ-Ai, SQ-Am and SQ-B).
It has some obvious scuffing but nothing serious and almost all around the edges, works perfectly; better than many. Perfectly ok to use.
This screen would be great in its own right as a focusing screen, or as a replacement for your existing damaged screen. Try finding another one!
