About the propeller, The propeller was produced by Sensenich, USA, but the history is not 100% clear. Decals are most likely retrofit ones. Red coloured tips could be dated from the “airclub’s life” of the prop or a result of the restoration. Red colour covers olive green one.  Model numer is 43K 10107 most likely. In private. Survived thanks to the pilot of the Airclub of Ostrów. Presented here thanks to Jacek Dzienisiuk.

Construction, The propeller lamination consists of five ash (most likely) plies. The outboard length of leading edge of approx. 600 mm and the tips have brass sheathing, while tips on the length of approx. 310 mm are covered with painted fabric (contemporarily paint).

Aircraft and Engine, The propeller was most likely used in Poland with one of ex-US Army Piper L4 Cub. It proves that some of American airscrews kept airworty status. The propeller was working with 4-cylinder Continental A-65-8 engine, boxer layout. Engine cubic capacity – 2,8l.
