Those who can answer, pat yourself on the back!
I have a P&S #2 Visual Quality Series IV lens, probably 12" or 13", it's not marked. The front lens is approx 3" in diameter. The exit lens is about 2.75 inches. The lens barrel is ~96mm from the very front to the back of the metal mounting flange for the lens board. The aperture goes from f4-f8 but one could move it to probably f32 or more but there are no markings for that. The lens only opens and closes. I guess in the studio, it was open for 5-20 seconds or more, so that was fine.
I'd like to be able to use the lens in daylight. I am considering what really low speed film for portraits, both B&W and color, is available besides Efke ASA 25 for use with a slow shutter of just 1/25 second. That's what a modern Packard shutter will go to!
Of course I could cut down something like a speed graphic and use the focal plane shutter from that in front of my P&S lens! However, that seems like a nightmare option. I could also use flash but that would be sad!
