Comments: According to the previous owner, this propeller was purchased from the Shuttleworth collection in England about 40 years ago by the owner's father. It is in pristine condition and is clearly stamped for the well-known Sopwith Camel, F1 Fighter using the 130 HP Clerget rotary engine, which was developed in 1913. The "Gun Timing" refers to the small marks on the hub edge used to time the interrupter for the Camel's machine gun. The smaller "AID" stamps are inspection stamps, commonly found on British manufactured propellers of that era. Original Camel propellers are difficult to find and are typically prized by collectors and others, and the absence of "G" and "N" stamped numbers indicate that this prop was manufactured before mid summer of 1917.
