Yes, 120, 6x6, and 4.5x6, with coupled rangefinder and internal rotating masks for the smaller format. Also it's a very heavy camera, much heavier than others of the same type I have here. The knurled ring under film advance knob is to actuate the viewfinder mask for 4.5x6 exposures. I guess it must have been expensive to buy when new, and probably produced in small numbers.
