This sale is for a mint condition Mamiya RB67 Accessory Shoe for the Multi Angle Grip. The grip is suitable for use on all RB67 and RZ67 cameras, and the accessory shoe mounts onto the top of the grip – or it is suitable for mounting directly onto a tripod if you want to.
This really rare accessory shoe allows you to position the flash or other accessory at almost any angle you want relative to the hand grip (or tripod). There are absolutely minimal signs of use.
