I'm looking for information on pre-visible Bowser pumps. This pump had a square base with a barrel middle which opened by sliding around the barrel to the right, it does not open like a door. Inside is the crank handle (wooden) and the nozzle. Up top is a pipe which the hose would connect to and would put the pumps height at approximately 5 feet. On the top side of this pipe, just above the hose connector something is missing, don't know what, but would like any help possible. I might be able to supply a photo. Thanks for any help. I know it is simular to th e Bowser pre-visible cast iron pump on page 81 of the value guide to gas station memorabilia. The major difference is how the door opens.
