This museum looked to be really interesting with a wide range of exhibits showcasing all facets of agriculture and farming. Fortunately, they also have a small but valuable collection of well preserved agricultural aircraft. The CSS-13 was the Polish licence version of the Polikarpov Po-2. It was built in Poland at WSK-Okęcie (370 frames) and WSK-Mielec (180 frames) from 1948-1955 and was in service, primarily as a crop sprayer, until 1968.
