This prop is from a Royal Naval Air Service Sopwith One-and-half
Strutter. The prop is made to a design of the Air Board of the
Admiralty and carries decals which state ‘Admiralty Design.’

The Sopwith Two Seater, as it was officially known, was
referred to as the Type 9400 by the RNAS. It was a landmark
design in WW1, the first tractor two-seater fighter and the first
British fighter to have a synchronized Vickers machine gun for the
pilot. Deliveries of the aircraft began to the RNAS in April 1916
and to the RFC in May. The RFC was in desperate need of a good
fighter at this time and many Naval Sopwith One-and-half Strutters were
transferred to the RFC. The nickname derives from the ‘w’ shaped
center section struts. 1500 were made in the UK and 4500 were made
under license in France. It was also used by the USA, Belgium and
Russia.
It was the dominant fighter for only six months, as the new Albatros
Scouts that appeared in September proved superior. Fortunately, by
this time, a smaller more agile derivative was in production, the Sopwith
Scout, known universally as the Sopwith Pup because it was
seen (correctly) as the son of the Sopwith One-and-half Strutter.
The leading ace in the aircraft was Captain
Geoffrey Cock MC who scored 13 victories on type.
This propeller is in restored condition. It was structurally
sound when we bought it and only attention to the finish has been
necessary.
