Machine story:

The original reason for buying this machine are the glass side windows, the crank and the registry display cover. But it turned out a style one machine, which had a different in length compared with the style three and six machines. Plan B was started due to this and the perfect functional condition of the machine. After partly successful removing the gray paint from the cover, the bottom plate and the print unit, the original black colour and chrome printing unit saw daylight again. The metal cover was widely blank and the paint remover affected the transparent paint top layer. I consider repainting the frame.

The machine was internally covered with a greasy brown layer and the keyboard under layer was black instead of the green colour which it should have (dust gathered in the last hundred years. Both are intensively cleaned and the perfectly preserved steel respectively green keyboard layer showed up. It deserves a collection place!
The frame is striped to the metal surface.The glass windows were fixed in dry out kit. The light force to the glass did not loosen them from the frame. While the reset knobs where removed, one glass window loosen due to the vibration of the frame. This with a little help did the others loosen as well. That gave the opportunity to repaint the frame in black.
Mount the windows in 1/2 millimetre felt glued to the frame. The rest of the machine was rebuild again to a nice new locking calculator.
