Good Evening, Hiernst,
For B & W copy work using 4 x 5, it's hard to beat Kodak Commercial--if you can locate any. Even if it's twenty years old or more, it will probably be in good shape. It develops well in HC-110B; contrast control is easy with adjustments in time. One major advantage to camera-copying old negatives instead on contact printing them is that cropping can easily be done.
