Here we have genuine, wooden, drone propellers, made by Sensenich. The company was initially established in 1932 as Sensenich Brothers to make aircraft propellers in Pennsylvania, and then expanded into airboat propellers in 1949, establishing a second factory for that market in Florida under the name Sensenich Wood Propeller Company. This fabulous drone propeller was made of laminated birch, back in 1945, and came with a Radioplane drone. So here’s your chance at aviation-coupled-with-Hollywood history! This propeller measures 41.5” x 6.25” x 3.5”, weighs 4 lbs
The first large-scale production, purpose-built drone was the product of Reginald Denny. He pursued his interest in radio control model aircraft in the 1930s. He, with business partners formed Reginald Denny Industries and opened a model plane shop in 1934 in Hollywood. The shop evolved into The Radioplane Company. Denny believed that low-cost RC aircraft would be very useful for training anti-aircraft gunners, and in 1935 he demonstrated a prototype target drone, the RP-1, to the US Army. Finally, in 1940, Denny and partners, won an US Army contract for their radio controlled RP-4, which became the Radioplane OQ-2. They manufactured nearly fifteen thousand drones for the army during World War II.
It just so happened that Army photographer David Conover was at the Van Nuys Radioplane factory in 1944, and saw a young lady named Norma Jeane, and the rest is luscious history… Yup, Marilyn Monroe worked at that factory, and mebbe she stroked your propeller.
