The first model is cylindrical, longer than the second model, and requires a double cable release to fire the mirror with the camera. The second model had three versions. All had a metal arm which extended from the Visoflex to the camera shutter button. Any lens which can focus to infinity on the Visoflex does not require exposure correction from infinity to about one meter. As you go closer, you have to make corrections. 2. The first bellows attaches only to the first Visoflex. It has scales of reproduction for the old 135mm lenses. The second model fits the second model Visoflexes only. It has scales of reproduction and exposure correction (red) for older 90mm lenses whose heads could be removed to mount on the bellows. It has a rack on the bottom for moving the whole bellows/camera combination. 3. For a lot more information see: http://elshaw.tripod.com/Visoflex/Visoflex.html and the 1962 edition of the Morgan & Morgan "Leica Manual." Best of luck on your entry to the Leica System.
