Miserable Model M View-Master From The 1980s
I've been a huge fan of View-Master 3D all my life. It wasn't until I was an adult that I discovered the older scenic reels. When View-Master started in 1939, it was originally intended for what we might today refer to as virtual sight seeing. It was decades later in the late 60s that the line morphed into being more of a childrens toy (admirable that the standard for the reels has stood throughout the product's entire lifetime. Any reel will mount into any viewer ever made).
The Model M viewer is from the late 80s and wasn't available for very long. I briefly thought that the Model M might have an advantage over more conventional viewers as the clear back would theoretically let in a lot of light. The transparent plastic is more to inspire the fascination of children as they watch the reel advancing mechanism work. As it turns out, the structure of the internals actually block out some of the image. Makes you wonder how this got off of the drawing board.
The curious shape is actually somewhat reminiscent of the first spindly View-Master Model A, so I guess it might be somewhat interesting for that reason. Though if using it occludes part of the dazzling 3D imagery within every View-Master reel, it's probably better to just put it back in the toy box.
View-Master reels that talk!
