...An excellent reproduction of the factory 911 RSR Bosch MFI pump, but not the real deal. Take a close look at the oil-supply line to the pump and how it is connected (yellow circle). You will note that this oil line is connected in a different location than the factory original BOSCH MFI RSR pump. The body of this BOSCH MFI pump was probably sourced from an early MB 260, physically the same part but in Aluminum not Magnesium (who cares!).
