For all Bolex H16 Cameras EL, EBM, SBM & RX-5 with 10x viewfinders
(Will also work with some Bolex cameras with the 13x viewfinder, but not all since some of the optics tubes in the 13x finders are slightly larger)
Simply take off the rubber eyecup from the Camera body & fasten the right angle finder in place with the 3 thumb screws. Image is not fully orientable, great accessory for when its difficult to get your eye to the viewfinder , especially with a 400' magazine.
