Here is a "Station Master" display pump. This is a model 145-4 with the "Vento" air eliminator and "See-gauge refill" ( that is the tube going from the top to the visi-gauge). The model 165-4 is the display pump without the "Vento" tube.
I have had this picture for a period of time and do not remember who originally posted it or were it is now.
