First of all I want to refer you to this page of my website where I list the histories of over 125 different companies that made a gas pump. Scroll down and read what information I have been about to attain about Kew-Ideal.
http://petrolianacollectibles.com/company_histories.htmI do have an ad on this page of my website that includes a round Kew-Ideal.
http://petrolianacollectibles.com/kew-ideal.htmI live in St. Louis where your pump was made, I drove to the location where it was made, but a more modern building is now there.
Even here in St. Louis, information about this company is few and far between. I have been to the St. Louis Public Library, no info, I have been to the Historical Museum, again no info. I actually have accumulated more info than either of them have.
At one time there were five companies here in St. Louis that made gas pumps in or around 1920, by 1931 they were all gone.
In my Gas Pump Identification book I have identified 12 items that they made, of the 12, 10 are gas pumps. I have identified a 10 gallon, Model 10 which is round, but they also made a square gas pump, Model No. unknown.
Since I have not identified the pump you have I ask you to please send me a picture of the pump and give me permission to add it in the 3rd Edition of the book that will be sent to the printers shortly.
