While the FK.31's service career in Finland was undistinguished, this machine made it to Latvia and Poland on an official visit by air force commander Väinö Vuori, the short man in flying garb. 3H-33, later KO-33, has a machine gun mounting in the rear cockpit here even though the Finns really only used the FK.31 as a trainer. NVI c/n 214 is painted on the nose and tail.
