I was building a nice Retina collection, although there are so many models and variations within each model that it made it impractical (financially) to continue. Plus, I started in with Zeiss Ikon, and that took me down a different path entirely.

The Retinas are on the second shelf and a few more on the bottom shelf.

I've sold several of the cameras seen here. Still have all of the Retinas and a couple more, too.
