I have WS 50mm, 90mm 135mm and 162mm, all are very good stopped down to F 8 or 11. Saying that I would not spend much time trying to find an adpator as there are many 90-105 enlarger lens with standard threads. I have an D3 and in the past have cut out thin sheets of plyboad drilled holes of the set screws and lens for lens board, painted flat black, then found a locking nut at the hardware store to hold the lens. As long as the wood does not warp will work.
