This sale is for a little used Mamiya 645 Pro manual winding crank suitable for the Mamiya 645 Super, Pro and ProTL cameras.
This crank has the winding knob on the crank arm missing, but is otherwise near mint; it is still very usable although of course not quite as good as on a complete crank with the knob still there. It works perfectly well and is far cheaper than a perfect condition crank.
Note that this crank is not suitable for any Mamiya cameras except the 645 Super, Pro and ProTL.
This is a great thing to have if you only have a motor drive – it does not run out of battery power (leaving you helpless) and weighs hardly anything. This crank has a slightly taller / higher raised section (where the crank arm sits) compared the the earlier Super version. This makes absolutely no difference at all if you are using the crank arm itself to advance the film, but if you are using this winder more as a winding knob (with the arm folded in) then it is just a lttle easier to use than the Super crank.
