Also included is my back up expolux, system , the main box is probably best for parts, with additional battery power supply, a 5x4 back, 5x4 bellows, 360 symmar lensr extra extension rail, and 10x8 bag bellows .

The camera and shutter work absolutely perfectly, if your not aware, you set you film stock and lens, then  use the exposure meter to measure the light that falls on the film plane, it meters for flash ambient or both, the expolux then sets the f stop and automatically shuts the shutter and stops down when the slide is loaded, the shutter is virtually silent and vibration free, it is  fool proof and means you do not need to bracket. As previously mentioned it is a unique pice of Swiss engineering that  will never be produced again.
