Nikkor-SW 75mm f4.5. I'm re-outfitting my LF/4x5 setup. I had one good lens (a 150 Schneider Symmar-S), and two usable but junky lenses (a 90mm angulon thats fine but a pain to use, and a Schneider 210mm with dented rings an a missing aperture indicator.) So this is a good wide (still need a lens board), and I have a Fujinon CM-W 250mm f6.3 arriving next week. The 90 Angulon I may save for a Wanderlust camera, just because its cheap and easy, and is designed for this lens. The 210 works, but has too much wrong with it to resell, so it will probably just go in a drawer.
