This sale is for a quite rare, near mint condition Mamiya C / RB67 / RZ67 Large Focus Knob suitable for the Mamiya C TLR cameras, and also fitting the RB67 and RZ67 series cameras as well.
This knob has only normal very minor signs of use – nothing that affects its use in any way. A great and simple aid to more accurate focusing – this large focus knob just slips over the camera focus wheel very easily. Yours for just £22.95.
