The older Omega D series had the alignment on the negative stage rather than on the lensboard. Which Durst do you have with an adjustable lens stage? Although the lensboard swings, the center detent on all the Durst enlargers 5x7 and bigger that I am familiar with is fixed in position. As far as I know the PROLA/DURST adjustable lensboard is a USA made aftermarket accessory.
