This sale is for a near mint condition Mamiya Tripod Adapter Collar 3/8″ to 1/4″. Ideal replacement if you have lost yours or a previous owner has removed it!
This adapter converts the built-in 3/8″ tripod socket in the base of your Mamiya camera to the more commonly used 1/4″ fitting and includes the special locking screw that stops the adapter from coming back out by accident. This adapter is the shorter type for thr 645 Super/Pro/ProTL cameras, with minimal signs of use, with cross-head locking screw rather than slot. Please note that this adapter can be used on the M645/RB/RZ models but is not recommened; it is likely that the locking screw will not rteach the threaded socket in the body.
Try finding another one – very hard to find.
