This sale is for one pair of very good condition rear lens and body caps to fit all RB67 (other than the 50mm f4.5) lenses, plus the RB67 ProSD and all RZ67 bodies.
These caps are genuine Mamiya, not an Indian or Chinese clone, and show only normal minor signs of use, just typical scuffs.
Plenty in stock – but just one listing here. If you want a few caps (or other sizes), just ask.
