16 mm Bell and Howell movie camera from the 50's

In trying to find out more about this 16 mm Bell and Howell movie camera, I came across your site. I haven't been able to find one like it so far and wonder if it is a common camera or if it is hard to find. My father used it during the 50's for family photographs. It accompanied him everywhere we went and documented family picnics, farm operations, and school programs. I remember seeing the camera case around his neck on horseback, in motor boats, and bouncing around on the front seat of the old farm pick-up truck. Brings back many fond memories . . .
