Sawyer Viewmaster, circa 1950. It works, though the lever that advances the picture sticks a bit on the return. There is also a hairline inside on the right pane - it moves when the lever is pressed down. Since this is inside, I cannot tell if it is a scratch or a hairline scratch. The reels can be viewed easily, and the images appear as they should.
Included are 30 reels from the "Wonders of the World" series. They all look as if they have rarely, if ever been used. Most are scenes from western states, though there is one of Geneva, Switzerland. We will soon have a list of reels - I can email it to you.
If you are only interested in reels, please ask for my list and make an offer for the ones you want.
