NEW Hersey Brass or Bronze Compound Water Meter Assembly 20303

  For sale is a NEW Hersey Brass or Bronze Water Meter Assembly.

  It is new old stock, sat around a lot and got dusty. However,
  all the bolt holes show no evidence of having been mounted.

  I do NOT know what it does but other people seem to be describing
  some sub-assemblies from this unit as a water meter. Holes are 
  still covered by blue protective plastic caps.

  Internal diameter of inlet and outlet holes is approximately 6 inches.
