Atlas-Warner Model 66 Slide Viewer.
Portable.
I believe this is 1960's era.
Good pre-owned condition. Has several scuffs and scratches on the case. The viewer does work. I am unsure if it has any focusing settings. Fully set up, the slide was somewhat blurry (see first Oliver tractor photo), but I was able to sharpen it when I lowered the viewer screen (see second Oliver tractor photo), but I had to do that by hand and hold it. I have no experience with this machine, so I may well be missing another way to focus. There are no instructions with the machine.
