In my new Gas Pump Bible book I list all the known companies that made a gas pump. There are over 215 companies listed (my first book had only 125). This is what I have found on Birmingham: "Birmingham Machine & Foundry Company. Birmingham, having started in business in 1883, didn't manufacture a gas pump until 1926. This was the only pump advertised by the company. It is unknown what happened to Birmingham."
