Sparrmann S 1-A, Sparrmannjagaren

There was no air force requirement for the aircraft, which was intended as an advanced trainer with performance similar to a fighter, but far cheaper. They were ordered anyway and given the designation P 1 where P=Prov (Trials). Several other aircraft were given P designations at first and then regular designations if they were adopted for service, but not this one.
Mostly, it didn't serve as a fighter trainer but as a general trainer and liasion aircraft.

The designer was Edmund Sparrmann, an Austrian who came to Sweden in 1919 in connection with the demonstration of Phönix D.III, shown in this photo, which was adopted as the first fighter in Swedish service and served with the army aviation and air force between 1919 and 1933.
