I am just finishing up what I think is an old Bowser lubester. There is a Bowser aluminum tag on it that said the model # is T 19. It measures aprox.30" high and 27" wide. There is a measuring rod inside the says 55 on the top so I am thinking the tank is 55 gallons. Would anyone know how old this thing is? Click on the images below to view this Bowser. Thanks for the help.
