I have a Flottorp Propeller, model 30.19 serial 3570 manufactured by Kinetics Inc. in Britt IA. I think this is just a prop used on a gas fan to inflate balloons but any other info would be appreciated.

You are on the right track. Flottorp desiged and made small engine propellers to fit 3-20hp engines such as Briggs & Stratton, Onan, Honda, Tecumseh, Hirth and more. A 30-19 was used mainly for the 5hp Briggs & Stratton and the Tecumseh engines. It probably was used for a ballon inflator but could have been used in other applications. Kinetics owed the Flottorp propeller line for a short time and I am not sure they actually manufactured anything. Again - history on Flottorp is very hard to come by.
I hope this helps.
