Hi Mike,
My camera has the plunger type shutter release at the bottom right (facing forward) of the shutter assembly, at the front of the camera, below the armature for the rangefinder window and focusing wheel. That shutter and focusing control location took a bit to become familiar, but now I find that when my right hand is well positioned for focusing or firing the shutter it is helping to stabilize the camera as well. My camera also does not have any double exposure prevention mechanism. It's a simple mechanical winder below the takeup spool with red window frame counting and nothing to keep you from winding past the next frame, or more should you really lose your concentration. Remarkably, despite the simplicity, the frame spacing is right on when the camera is correctly wound according to the frame numbers in the appropriate window.
