Jeff & Maz,

Thank you for your information.

Your prop is very probably from a WW1 reconnaissance aircraft from late 1917 or early 1918, the RE8. It is four bladed.

The data translates as;
D2971 The diameter of the prop in mm
P3170 The pitch of the propeller in mm
140hp RAF The 140hp engine designed and made by the Royal Aircraft Factory (hence RAF)

The key information is the drawing number, which you haven't mentioned, which is almost certainly T6296, where the designator letter T indicates the Royal Aircraft Factory.

With kind regards,
