Praktika made the Pentacon Super long after the KW brand had evolved and changed name but its roots are KW. KW also made the Pentacon 6 which was original known as a Praktisix.
This prism was exported to the US who insisted on the "Germany, USSR Occupied" marking.
The story of KW and John & Charles Noble is quite interesting, the company was very innovative making the first 35mm (full) system cameras, Exacta's never had motor drives and bulk backs.
The eye-cup fit is the same as the later Prakticamat and Nova, etc, cameras.
