Comments: This propeller design was used on both the Bristol F2B and the Airco DH9 using the Siddeley Puma engine, this one being stamped for the latter. It was manufactured by the Bristol and Colonial Aeroplane Company in Bristol, England, which was established in 1910. The drawing number AB7935 indicates that it was an Air Board design, as Bristol drawing numbers typically began with the letter "P". The DH9 was first flown in 1916 and followed the earlier model DH4. It was used during the end of WW1 and later powered by a 450 HP U.S. Liberty engine and designated DH9A.
This propeller is in excellent original condition with exceptionally well preserved decals on both blades.
