... thinking about making a CAMERA OBSCURA.... Big lens
I have an aerial camera lens. 14 lbs. 12" focus, f/2.5. (Twelve inches
is probably too short?) No shutter.
Please take it off my hands, give it a home. Anybody.
Drop by my house, take it away, or pay for shipping. Upstate NY.

The most critical component is probably the lens. It should probably
have a focal length of 500-800 mm and a diameter of at least 3 inches....

Also old aerial cameras used such focal lengths, and I have seen
surplus aerial camera lenses at surplus sites- bought a couple a
number of years ago.
