The View-Master Model M (#2053) was
produced by VMI (View-Master International Group) from 1986 until 1990. It is also known as the "push-button"
viewer and was available in red (some say pink!) and blue. It rotates the reel by depressing
the yellow button, accompanied by a loud 'click'. It cannot be described
as smooth at all. The original version of this viewer had a flaw whereby
part of the internal mechanism obscured the slide being viewed!
