Sensenich In Poland

Sensenich in Poland is strictly related to the purchase of Piper Cub aircraft at an early post IIWW time. These propellers which survived – together with the aircraft – external, 2 years, open – air storage in Germany were still in use in Polish Airclubs for a couple of subsequent years. Next, gradually replaced by Polish LWD copies.
