The Viso III has a rotating mount so you do not have to remove the finder or arm to mount it. You just put the Viso into place and rotate the lever. All Viso IIIs have a automatic return mirror with the dial as you describe. Most Viso IIs have a lever that you use to return the mirror after each shot. There were a small number of Viso IIs with the automatic return mirror of the later Viso III. They are known as a Viso IIa and are quite rare and expensive.
