This sale is for a very good condition Mamiya RB67 ProSD 120 6x7cm back suitable for use on any RB67 Pro, ProS or Pro SD camera.
This back is in very good overall condition. Cosmetically it is near mint; It has only minimal signs of use. Mechanically it works perfectly except that the return spring on winding arm is not working, so the winding arm stays sticking out and must be returned to the start position manually after advancing the film. Price reduced because of this. Apart fron this it works perfectly, fully tested. You get 10 6x7cm frames on one roll of 120 film.
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!
