This sale is for a really superb Mamiya RB67 ProSD 120 6x7cm back suitable for use on any RB67 Pro, ProS or Pro SD camera.
This back is in near mint condition. It is pretty much as new except for a small 1cm patch of missing lacquer on the top plate. Otherwise there are absolutely minimal signs of use.
The big thing about this back compared to the usual ProS back is that you do not have to worry about rotting light seals – this back does not use or need them.
Not so easy to find now as every RB user wants these backs – grab it quick before someone else does!
