I just found this, a grease gun I do believe. I can recall a gas station that had a white enamel lubrication station at the head of its service bay. On the rack were 4 or 6 variations of this grease gun. Gray, or Graco company built the first pressure lube equipment for servicing cars before WWII. Seems they still build a huge variety of pressure feed equipment for all types of industry. Anyone had one of these, or a set? Or the lube station? They were about six foot high, ten feet wide, with a lighted bench central, and doors to storage cabinets on both sides. I know where one is, and it would take a week, to get enough stuff cleared away to get a pic of it. There has to be more of these out there?
