For as long as I can remember my father and grandfather have had diesel and gas delivered for the tractors and farm equipment. The diesel goes in a large above ground tank on a platform while the gas goes into a below ground tank and is dispensed from a Sinclair pump. My grandfather never kept the globe on the top because ot could break and instead has the top covered with an old can. At some point someone asked for the globe and my grandfather gave it away because it was "useless" to him. My grandfather has passed on now but my father still uses the pump to fill the lawnmower and so on. I want to try to locate a globe for the pump and know that I need to find out what model and so forth. Where can I look to get some information on the old models and styles?
