MAMIYA RB 67 PRO revolving film adapter

[anthonym3]

I bought an RB 67 with no revolving film back adapter. It is the original model PRO. Will PRO-S adapters fit?

Good question.
The Reznitsky Compatibility chart doesn't answer that: http://www.reznitsky.info/Mamiya/Comchart.htm

The Pro S revolving adapter will not fit the Pro because the Pro S adapter has a pin on the front that connects to the camera body to change the viewfinder vanes for portrait/landscape mode

The Resnitsky chart I have appears to show it works unless I'm misreading it.

The "magazine" referenced there is the actual roll film holder. It's the G adapter that's missing from the OP's body.

-- and from the Reznitsky Comp table -- unfortunately.

IIRC, the opposite does work - you can put a Pro revolving adapter on a Pro-S body. You will lose some important interlocks though.

AFAIK, almost everything in the RB67 system is forward compatible -- Pro backs still work on a ProSD (albeit with only the original functionality of the Pro relative to double exposures and dark slide removal), earliest viewfinders will still work on the ProSD (any meter in the viewfinder is independent of the body), etc. I know for certain that Pro roll film holders (as well as Graflex 22/23/RH8/RH10/RH12/RH20 on the 2x3 Graflok mount) work fine with my ProS body and G adapter, with the same level of interlocks (none) that they had originally.

Going the other way doesn't always work, though, especially with the Pro (which lacked support for a lot of stuff we take for granted).
