  This is the 12" version. The 7" is much more common and
covers about 4x4. It was originally mounted in a camera
which could be hand held. While large and heavy it is
possible to mount one on a Speed Graphic providing some
auxilliary support is provided for the lens. This
arrangement was used for field work with low speed color
film in the late 1940's.  The back shutter of the Speed
Graphic eliminates the need for a shutter on the lens.
  I think the original aerial cameras had focal plane
shutters also.
  The 12" Aero Ektar is indeed a big chunk of glass.
