Ensign 220 Auto-Range
The Ensign 220 Auto-Range was introduced in the mid 1930s. Production was stopped during WW2 but restarted after the war up to 1949. This is a post war model with an Epsilon shutter.
It's a 6x6 or 6x4.5 folder with a coupled rangefinder. The focus lever is the bright one just top right of the lens. For both formats you wind the film using the red window to line up frame one. Then you close the red window and use the frame counter on the top (between the shutter release and the rangefinder window). This counter has two sides and can be flipped over to match the format you're using. There are fold away masks in the film gate and a slide over mask on the viewfinder (as can be seen here).
The rangefinder is out and I can't get the top off to fix it. The spring which stops you turning the wind on knob the wrong way is catching the top and I can't figure out how to get it out.
The slow speeds are also sticking unless I give them some exercise. The shutter needs cleaned out.
