For clarity, I have six different enlarging lenses (50mm, 60mm, 80mm, 90mm, 105mm 150mm) and nine different negative carriers (135, 6x4.5, 6x6, 6x7, 6x9, 4x5 glassless, 4x5 glass carrie, 6x6 speed glass carrier, 135 speed glassless carrier) for my D6. Each of the lenses has the matched lens plate. Every single lens and every single carrier would work in that enlarger. If my recollection is correct (but don't hold me to this), the condensers shown in the pictures would be sufficient to cover all those formats as well.
