A DIY 177mm f/8 Cooke triplet for 4x5 from off-the shelf lenses that YOU can build

Thanks for your answers! I have another question:

In your design you mention distances to the second lens. Are these distances to the center of the lens or to the edge? Is the convention to always do it one way or the other?

Yes, prescription thicknesses are always along the optical axis (airgaps and lens thicknesses are usually vertex to vertex, for example).
