The first unit to take the machine to France was No. 48 Squadron, which arrived there on March 8th, 1917.  The squadron's first offensive patrol was made on April 5th, 1917, but proved to be a disastrous debut.  The patrol consisted of six F.2As and was led by Captain Leefe-Robinson, V.C.  When over Douai, they were attacked by five Albatros D.IIIs led by Manfred von Richthofen, who shot down two of the Bristols for his thirty-fifth and thirty-sixth victories.  Richthofen’s pilots accounted for two other Bristols, one of them flown by Leefe-Robinson himself.

But the fault lay not in the Bristol.  In its earliest days, its crews made the serious tactical error of flying the machine in the accepted manner of the time for two-seaters; namely, as a platform for the observer's gun.  They failed to recognize the Bristol's supreme combat virtues of manoeuvrability and structural strength.

Fortunately, one or two pilots began more or less experimentally to fight the Bristol in the single-seater fashion, using the front gun as the primary weapon and leaving the observer to protect the tail.  These tactics were immediately successful, and were forthwith adopted by No. 48 Squadron and by No. 11, the second unit to receive Bristol Fighters.  The leading exponent of the Bristol Fighter was Lieutenant A. E. McKeever of No. 11 Squadron, who opened his scoring on June 29th, 1917 by shooting down an Albatros Scout.  McKeever shot down thirty-one aircraft in five months.

It was intended to fit the aircraft with Rolls-Royce engines but these were not being produced in sufficient quantities.  The realization of the excellence of the Bristol Fighter led to a substantial expansion of production of the type and by the autumn of 1917 it was obvious that Rolls Royce production would not be able to keep pace with the output of Bristol Fighters.  

Stock No: 2140

Alternative power units had to be considered, one of which was the Sunbeam Arab for which this prop was made.

Stock No: 2140

The batch number of the prop suggests that it was made early in 1918.  The prop is in newly restored condition and we have made a new hub plate.
