You are bidding on a FANTASTIC early example of a WW2 German Kriegsmarine / Luftwaffe Torpedo Propeller! This was used by various Aircraft and U-Boats that were equipped with the G7 Torpedo!
The G7e or more appropriately the G7e/T2, G7e/T3, and G7e/T4 Falke torpedoes were, with the exception of the T4 model, the standard torpedoes for Germany during World War II. All of the G7e models shared standardized dimensions for all German torpedoes designed for use by U-boats during World War II, they measured 53.3 cm (21 inches) in diameter, 7.16 m in length, and carried a Schießwolle 36 (a mixture of explosives) warhead of 280 kg. All were powered by 100 hp (75 kW) electric motors and lead-acid batteries which needed constant maintenance to maintain their reliability. Additionally, the batteries of these torpedoes needed to be preheated to a temperature of 30 °C (85 °F) to operate with maximum speed and range, though generally this was a non-issue as U-boats had the element of surprise and often had the advantage of firing the first shot.
Made of solid brass, this EARLY war Torpedo Prop is in VERY NICE condition! Some slight marks and wear due to the age (as well as a dent or two), but VERY solid otherwise! Also retains some hand-stamped part numbers. Mid-war, due to shortages in materials, the stopped making these in brass, and started to make them in steel. All the propellers you find nowadays are the late-war steel variant, that was left over after the war as they were used by Norway until the 1980’s – this is the EARLY WAR type, making it VERY RARE! Some very slight corrosion and patina as you can see in the photos…as well as some slight damage. There are some small inspection markings and stamps. This is the rear propeller of the two mounted, and have shown its location in the last photo. Could use a bit of clean-up, but otherwise a VERY nice and original item for any U-Boot/Kriegsmarine collection or restoration project!
