CSS 13 propeller, aircraft registration SP-YPB. Picture taken in hangar of Aeroklub Orląt,  Dęblin, about 2004. Non typically brass sheathing stayed not painted, while usually they were paint covered as well. SP-YPB is acually a replica which was built with utilisation of original parts in LZPN Krosno in 1992. This can be a reason why finishing of the prop is slightly different.. Photo: M.Peikert
