Ed,
Some caution is suggested here. If this is a second hand item similar to
what I messed with before, which was a 6-7 inch American made WWII Aerial
Camera lens & cell.... I found that those lenses needed a separate screw-on
cell containing a CORRECTOR lens in order to compensate for serious field
curvature and to give a flat picture of ground terrain.
Finding both of the matching cells could be a problem. I was never able to
find the vintage matching cell and later discarded it and the idea of making
a wide field film camera.
