Thanks a lot Rob. I used a Speed Graphic with a Leitz Hektor 120mm F2.5 Projector lens. The lens doesn't cover 4x5 (more like 6x7). I think one of the reasons is the lens tube, which is very long behind the last lens group. I will try to cut it off and see if I can turn the lens into a fast wide angle LF lens. The Film was Kodak, Tmax 100.
