About the propeller, The propeller was produced by Sensenich, USA. The history is not 100% clear. Decals are most likely retrofit ones. Red coloured tips could be dated back to the “airclub’s life” of the prop or a result of the restoration. Red painting covers olive green one.  Model number is 43K 10107, most likely. In private collection. 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).
