View-Master Viewers

View-Master Viewers

Since 1939 more than one billion View-Master® reels have been produced and sold except for three attempts at adding sound, all of the View-Master® reels function in any one of the reel viewers. 

So from the modern day focusing viewer and all the vintage viewers, the selection is plentiful. And the prices are usually a good index of the degree of collectibility not functionality to each model.
