The propeller of the Lublin R.XIII SP-AMG aircraft. The picture was taken during airfair flights in Sweedish Stokcholm – Bromma airport in 1936.
The propeller has a non standard feature: polished leading edge aluminium sheathing (the tonkilaque coating had been removed), most likely to improve the image of the demontrator aircraft.
The same propeller, Tonkilaque decal visible.
