Dick didn't mention, page 307, top left is of my Gas Pump Identification book. Don't leave home without it.
You have found a very early Wayne pump, it was made for long-distance, self-measuring, for gas or oils. I have a litte literature on it, email me for details.
I have a Wayne #1, (the first pump Wayne made) from 1902, and the pumping mechanism isn't much different.
