To fit an M39 screw mount, you will need a Rodagon 135/5.6. Don't know about the Durst enlarger, but my Rodagon 135/5.6 requires an extended lens board when used on my Beseler 45S.
Bottom line is that I doubt you will find a Rodagon, Componon S, or El-Nikkor 150 mm enlarger lens with an M39 screw mount. You may have to go to a 135 mm focal length. Even then, you should check whether your enlarger will work with it on a standard Durst lens board. Before you decide, you might want to read Chapter 6 "Enlarging Issues" in Post Exposure: Advanced Techniques for the Photographic Printer (2nd Edition) by Ctein. It's available free online. He evaluated all sorts of enlarging lenses including 4x5.
