About the propeller. The propeller was produced by Schwarz workshop, Berlin. The propeller is completely marked, the hub part indicates engine type, pitch (H – 145 cm) and diameter (D – 2400). Original decals were painted over and the central hub part was cut away – most likely to fit the clock in the middle.
Construction. The propeller lamination consists of 7 plies: 4 ash and 3 mahogany (?). The outboard length of leading edge had brass sheathing.
Aircraft and Engine. The propeller was powered by Siemens-Halske SH-14 radial engine.
