Although a fantasy pump, the closest thing I have found that it somewhat looks similar to is a specific Erie Clock Face Pump or a bowser 310. Possibly one of the places the creators got there inspiration from...Again still far from it but those pumps seem closer.
I dig mine too just because its my first ever pump. I will be way happier when I get my hands on a real one. Im a picker so eventually I will find a real one.
I at least think this was built in the USA so thats a start. Thanks again!
