What types of camera mounts are available for 6 by 9 view cameras with roll
fill backs? The baby graflock has a hinged ground glass screen which can be
swung out of the way to allow the roll film to be mounted, but there is
another one which has a slide in action ?. Also Calumet produce one with a
slide in action . I also think Arca make them , what type ?, are they
Swiss?.Any source info gratfully received?
