DescriptionThe machine consists of a wooden desk with an electric typewriter on the right and a cabinet with a Walther model 610 calculator inside it on the left with a panel of relay logic behind it.
There is a sliding panel and a shallow desk drawer (detached) below the typerwriter, and a sliding panel with a cutout above the cabintet door.
The typewriter has three columns of two thumbwheel switches in the back.
The calculator can slide out (though it is unsupported) on a custom welded steel frame. It appears to be modified so that the keys (still extant) are pressed by solenoids (likely from the typwriter keys), and the output is read out electrically (likely to the typewriter printer mechanism); no provision for paper appears to exist.
There is a bag loose parts attached: a cover for the typewriter, a small plastic case labelled "Pelikan", and miscellaneous brackets.
