This is an early version of Model MC17A, widely used in the detector section of mass spectrometers from Finnigan and/or Thermo Fisher. In the actual design the voltage dividing over the dynodes is done by thin film resistors directly printed on the ceramic spacers, but in elder designs a network of discrete resistors was used.

Special thanks to Stefan Rölke for identifying this device.
