[Morgała, A. (2003), pp.213-215] The final 30 were an improved variant H-19a, with the water radiator placed underneath the engine, as opposed of the original position above the engine. A total of 86 aircraft were used by the Polish Air Force until their withdrawal in 1935.
[ Single examples were also built by Hanriot for export to Japan and Czechoslovakia.
The aircraft was disliked by Polish pilots, as too difficult to fly for a trainer, among other difficulties demanding a precision landing. In addition, the water radiator was originally placed above the engine, which obstructed the view from the cockpit.][
