You know this calculator ? Sure, it is nothing else than a RFT MR4110 made in former GDR (German Democratic Republic) and sold as MBO MR4110.

MBO itself started already in the year 1973 producing calculators, view the exciting Junior. Later they brand labelled foreign products from Far East or GDR.

If you are curious about the history of a GDR-made calculator, search for the quality symbol. If you find the number 1 inside the letter "Q", known as "Gütezeichen Q" for ausgezeichnete Qualität [excellent quality], you know: 

This product was best export quality and quite often not sold within the country.

Thanks Tobias!
