This sale is for one difficult to find, very deformed but still usable rubber eyecup for any Mamiya later type RB67 / RZ67 prism finder – the RB67/RZ67 standard (type L2) non-metered prism, RB67 PD prism, RZ67 Pro PD and AE prisms and the RZ67 Pro II AE prism.
This eyecup is obviously distorted from storage but perfectly ok to use. Not the grestest but it still usable. And cheap!
Extremely hard to find in any condition. This one isn’t perfect but it is plenty good enough to use.
