Colde Stereo Viewer

Germany, 1950s

This viewer is very similar in style to our Rada Standard Box viewer, but has adjustable focus, making it fairly identical to the Rada-Standard II (not currently in our collection). This one came with a set of slides advertising a diner. You can see the metal mounts are the same Rada Standard mounts used in the Rada line. Every Colde viewer we’ve come across (and there have only been a few) has had commercial slides.
