I had alot of fun with my Durst-Zilla modification. You might enjoyy reading about it at www.BlueGrassHarvest.com I attached a Beseler CB7 to a Durst L184 chassis. That enlarger is long gone, now I have a standard L184 and a DeVere 504. I still have the special mounting bar that interfaces the CB7 with the Durst. Your enlarger looks great - reminds me of a 10X10 Saltzman enlarger with all that steel tubing. Nice work !
