Originally posted by Argenticien Interesting -- wouldn't that be an American lens? If so, I wonder whether Kodak had Nagel Werk ship lensless cameras across, and then bolted the Ektars on in Rochester; or if they shipped lenses to Stuttgart for Nagel to install. Maybe the former if this Retina model was sold mainly in USA, but the latter if it was sold from Stuttgart all over the world. In the days before modern supply chains,I don't quite understand the point of this exercise, when it seems like Nagel could have got any kind of lens somewhat locally in Germany, presumably including budget ones if that's what they were trying to accomplish with the Ektars.

Yes, it is an American made lens. Information on these lenses is quite scarce, and what little I've found has questionable sources.
From my research, I've found out that the 47/2 Ektar (Retina) is a symmetrical double gauss design, and it was only sold overseas at US Military PXs.
As to why they used American made lenses on German made cameras? That is a murkier question. I read something somewhere that directly after the war, Kodak AG in Stuttgart was producing cameras, but the Schneider and Rodenstock factories weren't up and running yet, so Kodak in NY supplied lenses for a brief time. This theory makes some sense, but is very questionable.
