About the Propeller Blade

This is a Hamilton Standard Licensed propeller manufactured by the Propeller Division of Sumitomo Metal Industries in Japan during WWII.   The decision to license these propellers to Japan prior to WWII was motivated by Hamilton Standard's desire to expand its business and generate revenue, as well as to promote international cooperation and peace.  At the time, the United States and Japan had not yet become enemies, and there was hope that economic ties between the two countries could help prevent war. 

However, as tensions between the United States and Japan increased in the years leading up to the war, the decision to license propeller technology to Japan came under scrutiny. Some critics accused Hamilton Standard of helping Japan build a stronger military, while others argued that the company should have been more cautious in sharing its technology with a potentially hostile nation.

Overall, the decision to license propeller technology to Japan during World War II remains a controversial and complex issue, with various factors contributing to the decision-making process at the time.

Propeller stands 64 inches tall x 11 inches wide. 

Propeller was polished and then anodized in gold (Some anodize has come off over the years)

About the Signatures on Blade

The signatures on this blade are absolutely gorgeous.  I'm amazed they were able to sign their names so perfectly and all in a line.  Would love to know which engraver they used for this.  After identifying as many names as we could we found (2) that particularly stood out (Charles Rogers and Joseph E. Kimm).  

Charles Rodgers (December 30, 1921 – disappeared June 23, 1965) was an American seismologist, pilot, and murder suspect who disappeared in June 1965 after police discovered the dismembered bodies of his elderly parents in the refrigerator of the Houston home all three shared, in what the media later dubbed "The Icebox Murders". Rogers has never been found and was declared dead in absentia in July 1975. He remains the only suspect in the murders, which are still considered unsolved.

Joseph E. Kimm (August 18,1911-September 19, 2013) an aviation pioneer. In 1933 he co-piloted Amelia Earhart's Northwest Airways Survey Flight.  Amelia Earhart rode along as an observer on a Northwest Airways survey flight to help convince Washington officials that a "Northern Transcontinental" route between Chicago and Seattle was feasible in winter.

 About the Mitsubishi G4M "Betty" Bomber

The Mitsubishi G4M was a twin-engine, land-based bomber aircraft used by the Imperial Japanese Navy during World War II. Nicknamed "Betty" by the Allies, the G4M was designed to have a long range, high speed, and heavy bomb load capacity, making it a key player in Japan's bombing campaigns across the Pacific. However, due to its lightweight construction and lack of armor protection, the G4M became known for its vulnerability to enemy fire and earned the unfortunate reputation as a "flying coffin."

This is the only example of this blade I have seen.
