I want information on the 210mm D-claron (not G-claron) lens. The front and rear elements are larger than the 210mm G-claron, so I think its coverage may be greater. Is this right? Will the 210 D-Claron cover 8x10, as the G-Claron does? What is the difference between a D-claron and a G-claron?

Never heard of it. There was a Repro-Claron which was a true process lens of Apo-Tessar type construction, with a coverage angle of about 50 degrees, but that was a smaller lens than the G-Claron.

The "G" in G-Claron stands for Graphic, since it was designed as a general purpose copy lens. I can't imagine what "D" would stand for.

I called Schnieder, and they have never heard of it!

Well with Rodenstock lenses D stands for duplicating as in the Apo Rodagon D series of lenses for slide and film duplication. Although 210 would be a tad long. The Apo D comes in 75 and 120 versions which cover 35mm to 4x5 film sizes.
