The Graphic View uses metal lens boards which are other
wise the same as the wooden ones for Anniversary Speed
Graphics. Well, there _is_ a difference. The wooden boards
are thick with a thiner border to fit the opening in the
camera. This provides a light trap. The metal boards have
constant thickness but have a raised boss around the holder
which fits into the front standard and provides the same
sort of light trap. However, the center of the board is
thinner so it can take some lenses with retaining rings or
the flange on the back that could not fit on a wood board
without undercutting.
For 4x5 cameras 4x4 inch boards of the Graphic wood type
will fit the Graphic View, the Burke & James press camera,
and the Calumet CC-400. However, the CC-400 boards will not
fit into the other cameras because it has a sliding lock on
both top and bottom and no taper on one edge. The lack of a
taper prevents the edge of the these boards from fitting
into the bottom of a Speed Graphic or Graphic view. Calumet
boards are flat, thin, and have a raised boss around the
edge but a much shallower one than the Graphic View board.
I think the rounded corners you mention must be for a
Pacemaker Graphic. These use a completly different design
made of stamped sheet metal with a bent down rim around the
edges. The rim forms a light trap. These boards will not fit
other cameras without an adaptor.
