This viewmaster viewer was made by the former Czechoslovakian company Meopta in the early sixties of the 20th century. It was the top viewer for Meopta, made from sturdy bakelite. The great designed viewer offers 7x magnification and focussing ability in the range from -5 to +3 diopters. Its not only a highly collectable viewer, but also a great viewer to use. It will offcourse take Meopta reels and original Viewmaster reels.
