Prop was restored, leaving originally numbers, date, producer and the engine type pressed on the hub. Pitch and diameter were already slightly tarnished. As all the inscriptions were already polished, they could not be repainted. The propeller was restored and , repainted and the sheathing placed again. Replica decals of IKAR and TONKILAQUE  VARSOVIE added. Now a part of private collection (2019).
