Hawthorne 4 Cylinder Air Pump Information Sought
Posted: Sun Mar 25, 2018 9:28 am
Just bought this Hawthorne 4 Cylinder hand Cranked Air Pump and wondered if anyone knew how to get more information about it's construction? It is missing some parts I may have to have cast and machined if anyone has any tips on that. It has a patent date of Nov.29 1910 but I can't find the patent. I'd really like to get this functional if anyone has any ideas or suggestions.
